RL Submitted (JAN-2018) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Catalyzes the hydrolytic deamination of adenine to
CC hypoxanthine. Plays an important role in the purine salvage pathway and
CC in nitrogen catabolism. {ECO:0000256|HAMAP-Rule:MF_01962}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=adenine + H(+) + H2O = hypoxanthine + NH4(+);
CC Xref=Rhea:RHEA:23688, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:16708, ChEBI:CHEBI:17368, ChEBI:CHEBI:28938; EC=3.5.4.2;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01962};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01962};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000256|HAMAP-Rule:MF_01962};
CC -!- SIMILARITY: Belongs to the metallo-dependent hydrolases superfamily.
CC Adenosine and AMP deaminases family. Adenine deaminase type 2
CC subfamily. {ECO:0000256|HAMAP-Rule:MF_01962}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:POR47014.1}.
