Comments [?]

Function Catalyzes the deamination of adenosine to inosine at the wobble position 34 of tRNA(Arg2).
Catalytic activity RHEA:43168: adenosine(34) in tRNA + H(+) + H2O = inosine(34) in tRNA + NH4(+)
EC 3.5.4.33
case <FTGroup:1>
Cofactor Zn(2+)
Note: Binds 1 zinc ion per subunit.
end case
Subunit Homodimer.
Similarity Belongs to the cytidine and deoxycytidylate deaminase family.
