CC Rule:MF_01281};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H(+) + H2O + S-methyl-5'-thioadenosine = NH4(+) + S-methyl-5'-
CC thioinosine; Xref=Rhea:RHEA:25025, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:17509, ChEBI:CHEBI:28938,
CC ChEBI:CHEBI:48595; EC=3.5.4.31; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_01281};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01281};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000256|HAMAP-Rule:MF_01281};
CC -!- SIMILARITY: Belongs to the metallo-dependent hydrolases superfamily.
CC ATZ/TRZ family. {ECO:0000256|ARBA:ARBA00006745}.
CC -!- SIMILARITY: Belongs to the metallo-dependent hydrolases superfamily.
CC MTA/SAH deaminase family. {ECO:0000256|HAMAP-Rule:MF_01281}.
