Function

Function:
Reversible hydration of carbon dioxide. Participates in pH regulation. May be involved in the control of cell proliferation and transformation. Appears to be a novel specific biomarker for a cervical neoplasia.
Catalytic Activity:
H(2)CO(3) = CO(2) + H(2)O.
Cofactor:
COFACTOR: Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
Enzyme Regulation:
ENZYME REGULATION: Inhibited by coumarins, saccharin, sulfonamide derivatives such as acetazolamide (AZA) and Foscarnet (phosphonoformate trisodium salt).
Active Site:
ACT_SITE 200 200 Proton acceptor.
