Function Catalyzes the hydrolytic deamination of adenosine and 2-deoxyadenosine.
Catalytic activity RHEA:24408: adenosine + H(+) + H2O = inosine + NH4(+)
EC 3.5.4.4
PhysiologicalDirection=left-to-right (RHEA:24409)
RHEA:28190: 2'-deoxyadenosine + H(+) + H2O = 2'-deoxyinosine + NH4(+)
EC 3.5.4.4
PhysiologicalDirection=left-to-right (RHEA:28191)
case <FTGroup:1>
Cofactor Zn(2+)
Note: Binds 1 zinc ion per subunit.
end case
Similarity Belongs to the metallo-dependent hydrolases superfamily. Adenosine and AMP deaminases family. Adenosine deaminase subfamily.
