CC   -!- FUNCTION: Catalyzes the deamination of adenosine to inosine at the
CC       wobble position 34 of tRNA(Arg2). {ECO:0000255|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:0000255|HAMAP-Rule:MF_00972};
CC   -!- COFACTOR:
CC       Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00972};
CC       Note=Binds 1 zinc ion per subunit. {ECO:0000255|HAMAP-Rule:MF_00972};
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00972}.
CC   -!- SIMILARITY: Belongs to the cytidine and deoxycytidylate deaminase
CC       family. {ECO:0000255|HAMAP-Rule:MF_00972}.
