>gnl|CDD|173833 cd00685, Trans_IPPS_HT, Trans-Isoprenyl Diphosphate Synthases,
head-to-tail. These trans-Isoprenyl Diphosphate
Synthases (Trans_IPPS) catalyze head-to-tail (HT) (1'-4)
condensation reactions. This CD includes all-trans
(E)-isoprenyl diphosphate synthases which synthesize
various chain length (C10, C15, C20, C25, C30, C35, C40,
C45, and C50) linear isoprenyl diphosphates from
precursors, isopentenyl diphosphate (IPP) and
dimethylallyl diphosphate (DMAPP). They catalyze the
successive 1'-4 condensation of the 5-carbon IPP to
allylic substrates geranyl-, farnesyl-, or
geranylgeranyl-diphosphate. Isoprenoid chain elongation
reactions proceed via electrophilic alkylations in which
a new carbon-carbon single bond is generated through
interaction between a highly reactive electron-deficient
allylic carbocation and an electron-rich carbon-carbon
double bond. The catalytic site consists of a large
central cavity formed by mostly antiparallel alpha
helices with two aspartate-rich regions (DDXX(XX)D)
located on opposite walls. These residues mediate
binding of prenyl phosphates via bridging Mg2+ ions,
inducing proposed conformational changes that close the
active site to solvent, protecting and stabilizing
reactive carbocation intermediates. Farnesyl diphosphate
synthases produce the precursors of steroids,
cholesterol, sesquiterpenes, farnsylated proteins, heme,
and vitamin K12; and geranylgeranyl diphosphate and
longer chain synthases produce the precursors of
carotenoids, retinoids, diterpenes, geranylgeranylated
chlorophylls, ubiquinone, and archaeal ether linked
lipids. Isoprenyl diphosphate synthases are widely
distributed among archaea, bacteria, and eukareya.

>gnl|CDD|173836 cd00867, Trans_IPPS, Trans-Isoprenyl Diphosphate Synthases.
Trans-Isoprenyl Diphosphate Synthases (Trans_IPPS) of
class 1 isoprenoid biosynthesis enzymes which either
synthesis geranyl/farnesyl diphosphates (GPP/FPP) or
longer chained products from isoprene precursors,
isopentenyl diphosphate (IPP) and dimethylallyl
diphosphate (DMAPP), or use geranyl (C10)-, farnesyl
(C15)-, or geranylgeranyl (C20)-diphosphate as
substrate. These enzymes produce a myriad of precursors
for such end products as steroids, cholesterol,
sesquiterpenes, heme, carotenoids, retinoids,
diterpenes, ubiquinone, and archaeal ether linked
lipids; and are widely distributed among archaea,
bacteria, and eukareya. The enzymes in this family share
the same 'isoprenoid synthase fold' and include the
head-to-tail (HT) IPPS which catalyze the successive
1'-4 condensation of the 5-carbon IPP to the growing
isoprene chain to form linear, all-trans, C10-, C15-,
C20- C25-, C30-, C35-, C40-, C45-, or C50-isoprenoid
diphosphates. The head-to-head (HH) IPPS catalyze the
successive 1'-1 condensation of 2 farnesyl or 2
geranylgeranyl isoprenoid diphosphates. Isoprenoid chain
elongation reactions proceed via electrophilic
alkylations in which a new carbon-carbon single bond is
generated through interaction between a highly reactive
electron-deficient allylic carbocation and an
electron-rich carbon-carbon double bond. The catalytic
site consists of a large central cavity formed by mostly
antiparallel alpha helices with two aspartate-rich
regions located on opposite walls. These residues
mediate binding of prenyl phosphates via bridging Mg2+
ions, inducing proposed conformational changes that
close the active site to solvent, stabilizing reactive
carbocation intermediates. Mechanistically and
structurally distinct, cis-IPPS are not included in this
CD.

>gnl|CDD|173830 cd00385, Isoprenoid_Biosyn_C1, Isoprenoid Biosynthesis enzymes,
Class 1. Superfamily of trans-isoprenyl diphosphate
synthases (IPPS) and class I terpene cyclases which
either synthesis geranyl/farnesyl diphosphates (GPP/FPP)
or longer chained products from isoprene precursors,
isopentenyl diphosphate (IPP) and dimethylallyl
diphosphate (DMAPP), or use geranyl (C10)-, farnesyl
(C15)-, or geranylgeranyl (C20)-diphosphate as
substrate. These enzymes produce a myriad of precursors
for such end products as steroids, cholesterol,
sesquiterpenes, heme, carotenoids, retinoids, and
diterpenes; and are widely distributed among archaea,
bacteria, and eukaryota.The enzymes in this superfamily
share the same 'isoprenoid synthase fold' and include
several subgroups. The head-to-tail (HT) IPPS catalyze
the successive 1'-4 condensation of the 5-carbon IPP to
the growing isoprene chain to form linear, all-trans,
C10-, C15-, C20- C25-, C30-, C35-, C40-, C45-, or
C50-isoprenoid diphosphates. Cyclic monoterpenes,
diterpenes, and sesquiterpenes, are formed from their
respective linear isoprenoid diphosphates by class I
terpene cyclases. The head-to-head (HH) IPPS catalyze
the successive 1'-1 condensation of 2 farnesyl or 2
geranylgeranyl isoprenoid diphosphates. Cyclization of
these 30- and 40-carbon linear forms are catalyzed by
class II cyclases. Both the isoprenoid chain elongation
reactions and the class I terpene cyclization reactions
proceed via electrophilic alkylations in which a new
carbon-carbon single bond is generated through
interaction between a highly reactive electron-deficient
allylic carbocation and an electron-rich carbon-carbon
double bond. The catalytic site consists of a large
central cavity formed by mostly antiparallel alpha
helices with two aspartate-rich regions located on
opposite walls. These residues mediate binding of prenyl
phosphates via bridging Mg2+ ions, inducing proposed
conformational changes that close the active site to
solvent, stabilizing reactive carbocation intermediates.
Generally, the enzymes in this family exhibit an
all-trans reaction pathway, an exception, is the
cis-trans terpene cyclase, trichodiene synthase.
Mechanistically and structurally distinct, class II
terpene cyclases and cis-IPPS are not included in this
CD.

>gnl|CDD|176187 cd05284, arabinose_DH_like, D-arabinose dehydrogenase. This group
contains arabinose dehydrogenase (AraDH) and related
alcohol dehydrogenases. AraDH is a member of the medium
chain dehydrogenase/reductase family and catalyzes the
NAD(P)-dependent oxidation of D-arabinose and other
pentoses, the initial step in the metabolism of
d-arabinose into 2-oxoglutarate. Like the alcohol
dehydrogenases, AraDH binds a zinc in the catalytic
cleft as well as a distal structural zinc. AraDH forms
homotetramers as a dimer of dimers. AraDH replaces a
conserved catalytic His with replace with Arg, compared
to the canonical ADH site. NAD(P)(H)-dependent
oxidoreductases are the major enzymes in the
interconversion of alcohols and aldehydes, or ketones.
Alcohol dehydrogenase in the liver converts ethanol and
NAD+ to acetaldehyde and NADH, while in yeast and some
other microorganisms ADH catalyzes the conversion
acetaldehyde to ethanol in alcoholic fermentation. ADH
is a member of the medium chain alcohol dehydrogenase
family (MDR), which has a NAD(P)(H)-binding domain in a
Rossmann fold of a beta-alpha form. The NAD(H)-binding
region is comprised of 2 structurally similar halves,
each of which contacts a mononucleotide. A GxGxxG motif
after the first mononucleotide contact half allows the
close contact of the coenzyme with the ADH backbone.
The N-terminal catalytic domain has a distant homology
to GroES. These proteins typically form dimers
(typically higher plants, mammals) or tetramers (yeast,
bacteria), and have 2 tightly bound zinc atoms per
subunit, a catalytic zinc at the active site and a
structural zinc in a lobe of the catalytic domain.
NAD(H) binding occurs in the cleft between the catalytic
and coenzyme-binding domains at the active site, and
coenzyme binding induces a conformational closing of
this cleft. Coenzyme binding typically precedes and
contributes to substrate binding. In human ADH
catalysis, the zinc ion helps coordinate the alcohol,
followed by deprotonation of a histidine, the ribose of
NAD, a serine, then the alcohol, which allows the
transfer of a hydride to NAD+, creating NADH and a
zinc-bound aldehyde or ketone. In yeast and some
bacteria, the active site zinc binds an aldehyde,
polarizing it, and leading to the reverse reaction.

(PKs), MAP kinase kinase(MAPKK) subfamily, fungal
Pek1-like proteins, catalytic (c) domain. PKs catalyze
the transfer of the gamma-phosphoryl group from ATP to

substrates. The MAPKK subfamily is part of a larger
superfamily that includes the catalytic domains of other
protein serine/threonine kinases, protein tyrosine
kinases, RIO kinases, aminoglycoside phosphotransferase,
choline kinase, and phosphoinositide 3-kinase. The
mitogen-activated protein (MAP) kinase signaling
pathways are important mediators of cellular responses
to extracellular signals. The pathways involve a triple
kinase core cascade comprising of the MAP kinase (MAPK),
which is phosphorylated and activated by a MAPK kinase
(MAPKK or MKK), which itself is phosphorylated and
activated by a MAPK kinase kinase (MAPKKK or MKKK).
Members of this group include the MAPKKs Pek1/Skh1 from
Schizosaccharomyces pombe and MKK2 from Saccharomyces
cerevisiae, and related proteins. Both fission yeast
Pek1 and baker's yeast MKK2 are components of the cell
integrity MAPK pathway. In fission yeast, Pek1
phosphorylates and activates the MAPK Pmk1/Spm1 and is
regulated by the MAPKKK Mkh1. In baker's yeast, the
pathway involves the MAPK Slt2, the MAPKKs MKK1 and
MKK2, and the MAPKKK Bck1. The cell integrity MAPK
cascade is activated by multiple stress conditions, and
is essential in cell wall construction, morphogenesis,
cytokinesis, and ion homeostasis.
