RL   Submitted (JUN-2007) 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:0000255|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:0000255|HAMAP-Rule:MF_01962};
CC   -!- COFACTOR:
CC       Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01962};
CC       Note=Binds 1 zinc ion per subunit. {ECO:0000255|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:0000255|HAMAP-Rule:MF_01962}.
