CC -!- FUNCTION: Catalyzes the deamination of adenosine to inosine at the
CC wobble position 34 of tRNA(Arg2). {ECO:0000256|HAMAP-Rule:MF_00972}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=adenosine(34) in tRNA + H(+) + H2O = inosine(34) in tRNA +
CC NH4(+); Xref=Rhea:RHEA:43168, Rhea:RHEA-COMP:10373, Rhea:RHEA-
CC COMP:10374, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:28938,
CC ChEBI:CHEBI:74411, ChEBI:CHEBI:82852; EC=3.5.4.33;
CC Evidence={ECO:0000256|ARBA:ARBA00001103, ECO:0000256|HAMAP-
CC Rule:MF_00972};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00972};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000256|HAMAP-Rule:MF_00972};
CC -!- SUBUNIT: Homodimer. {ECO:0000256|ARBA:ARBA00011738, ECO:0000256|HAMAP-
CC Rule:MF_00972}.
CC -!- SIMILARITY: Belongs to the cytidine and deoxycytidylate deaminase
CC family. ADAT2 subfamily. {ECO:0000256|ARBA:ARBA00010669}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
