>gnl|CDD|238200 cd00326, alpha_CA, Carbonic anhydrase alpha (vertebrate-like)
group. Carbonic anhydrases (CAs) are zinc-containing
enzymes that catalyze the reversible hydration of carbon
dioxide in a two-step mechanism: a nucleophilic attack
of a zinc-bound hydroxide ion on carbon dioxide,
followed by the regeneration of the active site by
ionization of the zinc-bound water molecule and removal
of a proton from the active site. They are ubiquitous
enzymes involved in fundamental processes like
photosynthesis, respiration, pH homeostasis and ion
transport. There are three evolutionary distinct groups
- alpha, beta and gamma carbonic anhydrases - which show
no significant sequence identity or structural
similarity. Most alpha CAs are monomeric enzymes. The
zinc ion is complexed by three histidine residues and a
fourth conserved histidine plays a potential role in
proton transfer.

>gnl|CDD|215000 smart01057, Carb_anhydrase, Eukaryotic-type carbonic anhydrase.
Carbonic anhydrases are zinc metalloenzymes which
catalyse the reversible hydration of carbon dioxide to
bicarbonate.. CAs have essential roles in facilitating
the transport of carbon dioxide and protons in the
intracellular space, across biological membranes and in
the layers of the extracellular space; they are also
involved in many other processes, from respiration and
photosynthesis in eukaryotes to cyanate degradation in
prokaryotes. There are five known evolutionarily
distinct CA families (alpha, beta, gamma, delta and
epsilon) that have no significant sequence identity and
have structurally distinct overall folds. Some CAs are
membrane-bound, while others act in the cytosol; there
are several related proteins that lack enzymatic
activity. The active site of alpha-CAs is well
described, consisting of a zinc ion coordinated through
3 histidine residues and a water molecule/hydroxide ion
that acts as a potent nucleophile. The enzyme employs a
two-step mechanism: in the first step, there is a
nucleophilic attack of a zinc-bound hydroxide ion on
carbon dioxide; in the second step, the active site is
regenerated by the ionisation of the zinc-bound water
molecule and the removal of a proton from the active
site. Beta- and gamma-CAs also employ a zinc hydroxide
mechanism, although at least some beta-class enzymes do
not have water directly coordinated to the metal ion.

animals, contains isozyme IV and similar proteins such
as mouse CA XV. Isozymes IV is attached to membranes via
a glycosylphosphatidylinositol (GPI) tail. In mammals,
Isozyme IV plays crucial roles in kidney and lung
function, amongst others. This subgroup also contains
the dual domain CA from the giant clam, Tridacna gigas.
T. gigas CA plays a role in the movement of inorganic
carbon from the surrounding seawater to the symbiotic
algae found in the clam's tissues. CA XV is expressed in
several species but not in humans or chimps. Similar to
isozyme CA IV, CA XV attaches to membranes via a GPI
tail.

monomeric enzymes. The zinc ion is complexed by three
histidines. This sub-family includes bacterial carbonic
anhydrase alpha, as well as plant enzymes such as
tobacco nectarin III and yam dioscorin and, carbonic
anhydrases from molluscs, such as nacrein, which are
part of the organic matrix layer in shells. Other
members of this family may be involved in maintaining pH
balance, in facilitating transport of carbon dioxide or
carbonic acid, or in sensing carbon dioxide levels in
the environment. Dioscorin is the major storage protein
of yam tubers and may play a role as an antioxidant.
Tobacco Nectarin may play a role in the maintenace of pH
and oxidative balance in nectar. Mollusc nacrein may
participate in calcium carbonate crystal formation of
the nacreous layer. This subfamily also includes three
alpha carbonic anhydrases from Chlamydomonas reinhardtii
(CAH 1-3). CAHs1-2 are localized in the periplasmic
space. CAH1 faciliates the movement of carbon dioxide
across the plasma membrane when the medium is alkaline.
CAH3 is localized to the thylakoid lumen and provides
CO2 to Rubisco.

>gnl|CDD|239392 cd03118, alpha_CA_V, Carbonic anhydrase alpha, CA isozyme V_like
subgroup. Carbonic anhydrases (CAs) are zinc-containing
enzymes that catalyze the reversible hydration of carbon
dioxide in a two-step mechanism: a nucleophilic attack
of a zinc-bound hydroxide ion on carbon dioxide,
followed by the regeneration of the active site by
ionization of the zinc-bound water molecule and removal
of a proton from the active site. They are ubiquitous
enzymes involved in fundamental processes like
photosynthesis, respiration, pH homeostasis and ion
transport. Most alpha CAs are monomeric enzymes. The
zinc ion is complexed by three histidines. This
vertebrate subgroup comprises isozyme V. CA V is the
mitochondrial isozyme, which may play a role in
gluconeogenesis and ureagenesis and possibly also in
lipogenesis.

of the penicillin binding proteins includes the member
from E. coli designated penicillin-binding protein 1C.
Members have both transglycosylase and transpeptidase
domains and are involved in forming cross-links in the
late stages of peptidoglycan biosynthesis. All members
of this subfamily are presumed to have the same basic
function [Cell envelope, Biosynthesis and degradation of
murein sacculus and peptidoglycan].
