>gnl|CDD|238673 cd01377, MYSc_type_II, Myosin motor domain, type II myosins. Myosin
II mediates cortical contraction in cell motility, and
is the motor in smooth and skeletal muscle. This
catalytic (head) domain has ATPase activity and belongs
to the larger group of P-loop NTPases. Myosins are
actin-dependent molecular motors that play important
roles in muscle contraction, cell motility, and
organelle transport. The head domain is a molecular
motor, which utilizes ATP hydrolysis to generate
directed movement toward the plus end along actin
filaments. A cyclical interaction between myosin and
actin provides the driving force. Rates of ATP
hydrolysis and consequently the speed of movement along
actin filaments vary widely, from about 0.04 micrometer
per second for myosin I to 4.5 micrometer per second for
myosin II in skeletal muscle. Myosin II moves in
discrete steps about 5-10 nm long and generates 1-5
piconewtons of force. Upon ATP binding, the myosin head
dissociates from an actin filament. ATP hydrolysis
causes the head to pivot and associate with a new actin
subunit. The release of Pi causes the head to pivot and
move the filament (power stroke). Release of ADP
completes the cycle.

>gnl|CDD|238675 cd01379, MYSc_type_III, Myosin motor domain, type III myosins.
Myosin III has been shown to play a role in the vision
process in insects and in hearing in mammals. Myosin
III, an unconventional myosin, does not form dimers.
This catalytic (head) domain has ATPase activity and
belongs to the larger group of P-loop NTPases. Myosins
are actin-dependent molecular motors that play important
roles in muscle contraction, cell motility, and
organelle transport. The head domain is a molecular
motor, which utilizes ATP hydrolysis to generate
directed movement toward the plus end along actin
filaments. A cyclical interaction between myosin and
actin provides the driving force. Rates of ATP
hydrolysis and consequently the speed of movement along
actin filaments vary widely, from about 0.04 micrometer
per second for myosin I to 4.5 micrometer per second for
myosin II in skeletal muscle. Myosin II moves in
discrete steps about 5-10 nm long and generates 1-5
piconewtons of force. Upon ATP binding, the myosin head
dissociates from an actin filament. ATP hydrolysis
causes the head to pivot and associate with a new actin
subunit. The release of Pi causes the head to pivot and
move the filament (power stroke). Release of ADP
completes the cycle.

>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|200566 cd10941, CE4_PuuE_HpPgdA_like_2, Putative catalytic domain of
uncharacterized prokaryotic polysaccharide deacetylases
similar to bacterial PuuE allantoinases and Helicobacter
pylori peptidoglycan deacetylase (HpPgdA). This family
contains many uncharacterized prokaryotic polysaccharide
deacetylases (DCAs) that show high sequence similarity
to the catalytic domain of bacterial PuuE allantoinases
and Helicobacter pylori peptidoglycan deacetylase
(HpPgdA). PuuE allantoinase appears to be
metal-independent and specifically catalyzes the
hydrolysis of (S)-allantoin into allantoic acid.
Different from PuuE allantoinase, HpPgdA has the ability
to bind a metal ion at the active site and is
responsible for a peptidoglycan modification that
counteracts the host immune response. Both PuuE
allantoinase and HpPgdA function as homotetramers. The
monomer is composed of a 7-stranded barrel with
detectable sequence similarity to the 6-stranded barrel
NodB homology domain of DCA-like proteins in the CE4
superfamily, which removes N-linked or O-linked acetyl
groups from cell wall polysaccharides. In contrast to
typical NodB-like DCAs, PuuE allantoinase and HpPgdA do
not exhibit a solvent-accessible polysaccharide binding
groove and might only bind a small molecule at the
active site.
