>gnl|CDD|163190 TIGR03234, OH-pyruv-isom, hydroxypyruvate isomerase. This enzyme
interconverts tartronate semi-aldehyde (TSA, aka
2-hydroxy 3-oxopropionate) and hydroxypyruvate. The E.
coli enzyme has been characterized and found to be
specific for TSA, contain no cofactors, and have a
rather high Km for hydroxypyruvate of 12.5 mM. The gene
is ofter found in association with glyoxalate
carboligase (which produces TSA), but has been shown to
have no effect on growth on glyoxalate when knocked out.
This is consistent with the fact that the gene for
tartronate semialdehyde reductase (glxR) is also
associated and may have primary responsibility for the
catabolism of TSA.

>gnl|CDD|189005 cd09598, M4_uncharacterized, Peptidase M4 family containing mostly
uncharacterized proteins. This family of
uncharacterized bacterial proteins are homologs of the
M4 peptidase family that is also known as the
thermolysin-like peptidase (TLP) family. Typically, the
M4 peptidases consist of a presequence (signal
sequence), a propeptide sequence and a peptidase unit.
The presequence is cleaved off during export while the
propeptide has inhibitory and chaperone functions and
facilitates folding. The propeptide remains attached
until the peptidase is secreted and can be safely
activated. All peptidases in this family bind a single
catalytic zinc ion which is tetrahedrally co-ordinated
by three amino acid ligands and a water molecule that
forms the nucleophile on activation during catalysis.
TLPs are secreted eubacterial endopeptidases from
Gram-positive or Gram-negative sources that degrade
extracellular proteins and peptides for bacterial
nutrition. They contain HEXXH and EXXXD motifs as part
of their active site and belong to the Glu-zincins
family and are selectively inhibited by Steptomyces
metalloproteinase inhibitor (SMPI) as well as by
phosphoramidon from Streptomyces tanashiensis. A large
number of these enzymes are implicated as key factors in
the pathogenesis of various diseases, including
gastritis, peptic ulcer, gastric carcinoma, cholera and
several types of bacterial infections, and are therefore
important drug targets. Some enzymes of the family can
function at extremes of temperatures, while some
function in organic solvents, thus rendering them novel
targets for biotechnological applications.

>gnl|CDD|143522 cd06964, NR_DBD_RAR, DNA-binding domain of retinoic acid receptor
(RAR) is composed of two C4-type zinc fingers.
DNA-binding domain of retinoic acid receptor (RAR) is
composed of two C4-type zinc fingers. Each zinc finger
contains a group of four Cys residues which co-ordinates
a single zinc atom. RAR interacts with specific DNA
sites upstream of the target gene and modulates the rate
of transcriptional initiation. RARs mediate the
biological effect of retinoids, including both natural
dietary vitamin A (retinol) metabolites and active
synthetic analogs. Retinoids play key roles in a wide
variety of essential biological processes, such as
vertebrate embryonic morphogenesis and organogenesis,
differentiation and apoptosis, and homeostasis. RAR
function as a heterodimer with retinoic X receptor by
binding to specific RAR response elements (RAREs), which
are composed of two direct repeats of the consensus
sequence 5'-AGGTCA-3' separated by one to five base pair
and found in the promoter regions of retinoid target
genes. Like other members of the nuclear receptor (NR)
superfamily of ligand-activated transcription factors,
retinoic acid receptors have a central well conserved
DNA binding domain (DBD), a variable N-terminal domain,
a non-conserved hinge and a C-terminal ligand binding
domain (LBD).

domain family is part of a larger superfamily that
includes the catalytic domains of other kinases such as
the typical serine/threonine/tyrosine protein kinases
(PKs), aminoglycoside phosphotransferase, choline

the gamma-phosphoryl group from ATP to the 3-hydroxyl of
the inositol ring of D-myo-phosphatidylinositol (PtdIns)
or its derivatives. PI3Ks play an important role in a
variety of fundamental cellular processes, including
cell motility, the Ras pathway, vesicle trafficking and
secretion, immune cell activation and apoptosis. They
can be divided into three main classes (I, II, and III),
defined by their substrate specificity, regulation, and
domain structure. Class II PI3Ks preferentially use
PtdIns as a substrate to produce PtdIns(3)P, but can
also phosphorylate PtdIns(4)P. They function as monomers
and do not associate with any regulatory subunits. Class
II enzymes contain an N-terminal Ras binding domain, a
lipid binding C2 domain, a PI3K homology domain of
unknown function, an ATP-binding cataytic domain, a Phox
homology (PX) domain, and a second C2 domain at the
C-terminus. The class II alpha isoform, PI3K-C2alpha,
plays key roles in clathrin assembly and
clathrin-mediated membrane trafficking, insulin
signaling, vascular smooth muscle contraction, and the
priming of neurosecretory granule exocytosis.
