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.

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.

the nacreous layer. This subfamily also includes three

>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.

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.

are sequence similar to carbonic anhydrases. Carbonic
anhydrases are zinc-containing enzymes that catalyze the

mechanism. CARPs have lost conserved histidines involved
in zinc binding and consequently their catalytic

processes of the central nervous system, and could be
involved in protein-protein interactions. CARP VIII has
been shown to bind inositol 1,4,5-triphosphate (IP3)
receptor type I (IP3RI), reducing the affinity of the
receptor for IP3. IP3RI is an intracellular IP3-gated
Ca2+ channel located on intracellular Ca2+ stores. IP3RI
converts IP3 signaling into Ca2+ signaling thereby
participating in a variety of cell functions.
