>gnl|CDD|176533 cd08591, PI-PLCc_beta, Catalytic domain of metazoan
phosphoinositide-specific phospholipase C-beta. This
subfamily corresponds to the catalytic domain present in
metazoan phosphoinositide-specific phospholipase C
(PI-PLC, EC 3.1.4.11)-beta isozymes. PI-PLC is a
signaling enzyme that hydrolyzes the membrane
phospholipids phosphatidylinositol-4,5-bisphosphate
(PIP2) to generate two important second messengers in
eukaryotic signal transduction cascades, Inositol
1,4,5-trisphosphate (InsP3) and diacylglycerol (DAG).
InsP3 triggers inflow of calcium from intracellular
stores, while DAG, together with calcium, activates
protein kinase C, which goes on to phosphorylate other
molecules, leading to altered cellular activity. Calcium
is required for the catalysis. PLC-beta represents a
class of mammalian PI-PLC that has an N-terminal
pleckstrin homology (PH) domain, an array of EF hands, a
PLC catalytic core domain, a C2 domain, and a unique
C-terminal coiled-coil (CT) domain necessary for
homodimerization. The PLC catalytic core domain is a TIM
barrel with two highly conserved regions (X and Y) split
by a highly degenerate linker sequence. There are four
PLC-beta isozymes (1-4). They are activated by the
heterotrimeric G protein alpha q subunits through their
C2 domain and long C-terminal extension. The beta-gamma
subunits of heterotrimeric G proteins are known to
activate the PLC-beta2 and -beta3 isozymes only. Aside
from four PLC-beta isozymes identified in mammals, some
eukaryotic PLC-beta homologs have been classified into
this subfamily, such as NorpA and PLC-21 from Drosophila
and PLC-beta from turkey, Xenopus, sponge, and hydra.

>gnl|CDD|176501 cd08558, PI-PLCc_eukaryota, Catalytic domain of eukaryotic
phosphoinositide-specific phospholipase C and similar
proteins. This family corresponds to the catalytic
domain present in eukaryotic phosphoinositide-specific
phospholipase C (PI-PLC, EC 3.1.4.11) and similar
proteins. The higher eukaryotic PI-PLCs play a critical
role in most signal transduction pathways, controlling
numerous cellular events such as cell growth,
proliferation, excitation and secretion. They strictly
require Ca2+ for the catalytic activity. They display a
clear preference towards the hydrolysis of the more
highly phosphorylated membrane phospholipids
PI-analogues, phosphatidylinositol 4,5-bisphosphate
(PIP2) and phosphatidylinositol-4-phosphate (PIP), to
generate two important second messengers in eukaryotic
signal transduction cascades, inositol
1,4,5-trisphosphate (InsP3) and diacylglycerol (DAG).
InsP3 triggers inflow of calcium from intracellular
stores, while DAG, together with calcium, activates
protein kinase C, which then phosphorylates other
molecules, leading to altered cellular activity. The
eukaryotic PI-PLCs have a multidomain organization that
consists of a PLC catalytic core domain, and various
regulatory domains, such as the pleckstrin homology (PH)
domain, EF-hand motif, and C2 domain. The catalytic core
domain is a TIM barrel with two highly conserved regions
(X and Y) split by a linker region. The catalytic
mechanism of eukaryotic PI-PLCs is based on general base
and acid catalysis utilizing two well conserved
histidines and consists of two steps, a phosphotransfer
and a phosphodiesterase reaction. The mammalian PI-PLCs
consist of 13 isozymes, which are classified into
six-subfamilies, PI-PLC-delta (1,3 and 4), -beta(1-4),
-gamma(1,2), -epsilon, -zeta, and -eta (1,2). Ca2+ is
required for the activation of all forms of mammalian
PI-PLCs, and the concentration of calcium influences
substrate specificity. This family also includes
metazoan phospholipase C related but catalytically
inactive proteins (PRIP), which belong to a group of
novel inositol trisphosphate binding proteins. Due to
the replacement of critical catalytic residues, PRIP
does not have PLC enzymatic activity.

is relatively well characterized. It is activated by
high calcium levels generated by other PI-PLC family
members, and therefore functions as a calcium amplifier
within the cell. Different PI-PLC-delta isozymes have
different tissue distribution and different subcellular
locations. PI-PLC-delta1 is mostly a cytoplasmic
protein, PI-PLC-delta3 is located in the membrane, and
PI-PLC-delta4 is predominantly detected in the cell

InsP3 triggers inflow of calcium from intracellular

is required for the catalysis. The prototype of this CD
is protein Plc1p encoded by PLC1 genes from
Saccharomyces cerevisiae. Plc1p contains both highly
conserved X- and Y- regions of PLC catalytic core
domain, as well as a presumptive EF-hand like calcium
binding motif. Experiments show that Plc1p displays
calcium dependent catalytic properties with high
similarity to those of the mammalian PLCs, and plays
multiple roles in modulating the membrane/protein
interactions in filamentation control. CaPlc1p encoded
by CAPLC1 from the closely related yeast Candida
albicans, an orthologue of S. cerevisiae Plc1p, is also
included in this group. Like Plc1p, CaPlc1p has
conserved presumptive catalytic domain, shows PLC
activity when expressed in E. coli, and is involved in
multiple cellular processes. There are two other gene
copies of CAPLC1 in C. albicans, CAPLC2 (also named as
PIPLC) and CAPLC3. Experiments show CaPlc1p is the only
enzyme in C. albicans which functions as PLC. The
biological functions of CAPLC2 and CAPLC3 gene products
must be clearly different from CaPlc1p, but their exact
roles remain unclear. Moreover, CAPLC2 and CAPLC3 gene
products are more similar to extracellular bacterial
PI-PLC than to the eukaryotic PI-PLC, and they are not
included in this subfamily.

subfamily corresponds to the catalytic domain present in
prokaryotic and eukaryotic phosphoinositide-specific
phospholipase C (PI-PLC), which is a ubiquitous enzyme
catalyzing the cleavage of the sn3-phosphodiester bond
in the membrane phosphoinositides (phosphatidylinositol,
PI; Phosphatidylinositol-4-phosphate, PIP;
phosphatidylinositol 4,5-bisphosphate, PIP2) to yield
inositol phosphates (inositol monosphosphate, InsP;
inositol diphosphate, InsP2; inositol trisphosphate,
InsP3) and diacylglycerol (DAG). The higher eukaryotic
PI-PLCs (EC 3.1.4.11) have a multidomain organization
that consists of a PLC catalytic core domain, and
various regulatory domains. They play a critical role in
most signal transduction pathways, controlling numerous
cellular events, such as cell growth, proliferation,
excitation and secretion. These PI-PLCs strictly require
Ca2+ for their catalytic activity. They display a clear
preference towards the hydrolysis of the more highly
phosphorylated PI-analogues, PIP2 and PIP, to generate
two important second messengers, InsP3 and DAG. InsP3
triggers inflow of calcium from intracellular stores,
while DAG, together with calcium, activates protein
kinase C, which then phosphorylates other molecules,
leading to altered cellular activity. In contrast,
bacterial PI-PLCs contain a single catalytic domain.
Although their precise physiological function remains
unclear, bacterial PI-PLCs may function as virulence
factors in some pathogenic bacteria. They participate in
Ca2+-independent PI metabolism. They are characterized
as phosphatidylinositol-specific phospholipase C (EC
4.6.1.13) that selectively hydrolyze PI, not PIP or
PIP2. The TIM-barrel type catalytic domain in bacterial
PI-PLCs is very similar to the one in eukaryotic
PI-PLCs, in which the catalytic domain is assembled from
two highly conserved X- and Y-regions split by a
divergent linker sequence. The catalytic mechanism of
both prokaryotic and eukaryotic PI-PLCs is based on
general base and acid catalysis utilizing two well
conserved histidines, and consists of two steps, a
phosphotransfer and a phosphodiesterase reaction. This
superfamily also includes a distinctly different type of
eukaryotic PLC, glycosylphosphatidylinositol-specific
phospholipase C (GPI-PLC), an integral membrane protein
characterized in the protozoan parasite Trypanosoma
brucei. T. brucei GPI-PLC hydrolyzes the GPI-anchor on
the variant specific glycoprotein (VSG), releasing
dimyristyl glycerol (DMG), which may facilitate the
evasion of the protozoan to the host#s immune system. It
does not require Ca2+ for its activity and is more
closely related to bacterial PI-PLCs, but not mammalian
PI-PLCs.

>gnl|CDD|176541 cd08599, PI-PLCc_plant, Catalytic domain of plant
phosphatidylinositide-specific phospholipases C. This
family corresponds to the catalytic domain present in a
group of phosphoinositide-specific phospholipases C
(PI-PLC, EC 3.1.4.11) encoded by PLC genes from higher
plants, which are homologs of mammalian PI-PLC in terms
of overall sequence similarity and domain organization.
Mammalian PI-PLC is a signaling enzyme that hydrolyzes
the membrane phospholipids
phosphatidylinositol-4,5-bisphosphate (PIP2) to
generate two important second messengers in eukaryotic
signal transduction cascades, inositol
1,4,5-trisphosphate (InsP3) and diacylglycerol (DAG).
InsP3 triggers inflow of calcium from intracellular
stores, while DAG, together with calcium, activates
protein kinase C, which then phosphorylates other
molecules, leading to altered cellular activity. Calcium
is required for the catalysis. The domain arrangement of
plant PI-PLCs is structurally similar to the mammalian
PLC-zeta isoform, which lacks the N-terminal pleckstrin
homology (PH) domain, but contains EF-hand like motifs
(which are absent in a few plant PLCs), a PLC catalytic
core domain with X- and Y- highly conserved regions
split by a linker sequence, and a C2 domain. However, at
the sequence level, the plant PI-PLCs are closely
related to the mammalian PLC-delta isoform. Experiments
show that plant PLCs display calcium dependent PLC
catalytic properties, although they lack some of the
N-terminal motifs found in their mammalian counterparts.
A putative calcium binding site may be located at the
region spanning the X- and Y- domains.

phosphodiesterases superfamily. The PI-PLC-like
phosphodiesterases superfamily represents the catalytic
domains of bacterial phosphatidylinositol-specific
phospholipase C (PI-PLC, EC 4.6.1.13), eukaryotic
phosphoinositide-specific phospholipase C (PI-PLC, EC

(GP-GDE, EC 3.1.4.46), sphingomyelinases D (SMases D)
(sphingomyelin phosphodiesterase D, EC 3.1.4.41) from
spider venom, SMases D-like proteins, and phospholipase
D (PLD) from several pathogenic bacteria, as well as
their uncharacterized homologs found in organisms
ranging from bacteria and archaea to metazoans, plants,
and fungi. PI-PLCs are ubiquitous enzymes hydrolyzing
the membrane lipid phosphoinositides to yield two
important second messengers, inositol phosphates and
diacylglycerol (DAG). GP-GDEs play essential roles in
glycerol metabolism and catalyze the hydrolysis of
glycerophosphodiesters to sn-glycerol-3-phosphate (G3P)
and the corresponding alcohols that are major sources of
carbon and phosphate. Both, PI-PLCs and GP-GDEs, can
hydrolyze the 3'-5' phosphodiester bonds in different
substrates, and utilize a similar mechanism of general
base and acid catalysis with conserved histidine
residues, which consists of two steps, a phosphotransfer
and a phosphodiesterase reaction. This superfamily also
includes Neurospora crassa ankyrin repeat protein NUC-2
and its Saccharomyces cerevisiae counterpart, Phosphate
system positive regulatory protein PHO81,
glycerophosphodiester phosphodiesterase (GP-GDE)-like
protein SHV3 and SHV3-like proteins (SVLs). The residues
essential for enzyme activities and metal binding are
not conserved in these sequence homologs, which might
suggest that the function of catalytic domains in these
proteins might be distinct from those in typical
PLC-like phosphodiesterases.

>gnl|CDD|130712 TIGR01651, CobT, cobaltochelatase, CobT subunit. This model
describes Pseudomonas denitrificans CobT gene product,
which is a cobalt chelatase subunit that functions in
cobalamin biosynthesis. Cobalamin (vitamin B12) can be
synthesized via several pathways, including an aerobic
pathway (found in Pseudomonas denitrificans) and an
anaerobic pathway (found in P. shermanii and Salmonella
typhimurium). These pathways differ in the point of
cobalt insertion during corrin ring formation. There are
apparently a number of variations on these two pathways,
where the major differences seem to be concerned with
the process of ring contraction. Confusion regarding the
functions of enzymes found in the aerobic vs. anaerobic
pathways has arisen because nonhomologous genes in these
different pathways were given the same gene symbols.
Thus, cobT in the aerobic pathway (P. denitrificans) is
not a homolog of cobT in the anaerobic pathway (S.
typhimurium). It should be noted that E. coli
synthesizes cobalamin only when it is supplied with the
precursor cobinamide, which is a complex intermediate.
Additionally, all E. coli cobalamin synthesis genes
(cobU, cobS and cobT) were named after their Salmonella
typhimurium homologs which function in the anaerobic
cobalamin synthesis pathway. This model describes the
aerobic cobalamin pathway Pseudomonas denitrificans CobT
gene product, which is a cobalt chelatase subunit, with
a MW ~70 kDa. The aerobic pathway cobalt chelatase is a
heterotrimeric, ATP-dependent enzyme that catalyzes
cobalt insertion during cobalamin biosynthesis. The
other two subunits are the P. denitrificans CobS
(TIGR01650) and CobN (pfam02514 CobN/Magnesium
Chelatase) proteins. To avoid potential confusion with
the nonhomologous Salmonella typhimurium/E.coli cobT
gene product, the P. denitrificans gene symbol is not
used in the name of this model [Biosynthesis of
cofactors, prosthetic groups, and carriers, Heme,
porphyrin, and cobalamin].

>gnl|CDD|221185 pfam11719, Drc1-Sld2, DNA replication and checkpoint protein.
Genome duplication is precisely regulated by
cyclin-dependent kinases CDKs, which bring about the
onset of S phase by activating replication origins and
then prevent relicensing of origins until mitosis is
completed. The optimum sequence motif for CDK
phosphorylation is S/T-P-K/R-K/R, and Drc1-Sld2 is found
to have at least 11 potential phosphorylation sites.
Drc1 is required for DNA synthesis and S-M replication
checkpoint control. Drc1 associates with Cdc2 and is
phosphorylated at the onset of S phase when Cdc2 is
activated. Thus Cdc2 promotes DNA replication by
phosphorylating Drc1 and regulating its association with
Cut5. Sld2 and Sld3 represent the minimal set of S-CDK
substrates required for DNA replication.
