>gnl|CDD|239395 cd03121, alpha_CARP_X_XI_like, Carbonic anhydrase alpha related
protein: groups X, XI and related proteins. This
subgroup contains carbonic anhydrase related proteins
(CARPs) X and XI, which have been implicated in various
biological processes of the central nervous system.
CARPs are sequence similar to carbonic anhydrases.
Carbonic anhydrases are zinc-containing enzymes that
catalyze the reversible hydration of carbon dioxide in a
two-step mechanism. CARPs have lost conserved histidines
involved in zinc binding and consequently their
catalytic activity. CARP XI plays a role in the
development of gastrointestinal stromal tumors.

>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.

of yam tubers and may play a role as an antioxidant.
Tobacco Nectarin may play a role in the maintenace of pH

participate in calcium carbonate crystal formation of
the nacreous layer. This subfamily also includes three
alpha carbonic anhydrases from Chlamydomonas reinhardtii

across the plasma membrane when the medium is alkaline.
CAH3 is localized to the thylakoid lumen and provides
CO2 to Rubisco.

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. Alpha CAs are
strictly monomeric enzymes. The zinc ion is complexed by
three histidine residues. This sub-family comprises the
membrane protein CA IX. CA IX is functionally implicated
in tumor growth and survival. CA IX is mainly present in
solid tumors and its expression in normal tissues is
limited to the mucosa of alimentary tract. CA IX is a
transmembrane protein with two extracellular domains:
carbonic anhydrase and, a proteoglycan-like segment
mediating cell-cell adhesion. There is evidence for an
involvement of the MAPK pathway in the regulation of CA9
expression.

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. This sub-family comprises the
secreted CA VI, which is found in saliva.

protein. Members of this protein family, to date, are
found in a completed prokaryotic genome if and only if
the species is one of the archaeal methanogens. It is a
radical SAM enzyme by homology. The exact function is
unknown, but likely is linked to methanogenesis. In
most genomes, the member of this family is encoded by a
gene next to, and divergently transcribed from, the
methyl coenzyme M reductase operon.
