tRNA (guanine(27)-N2)-dimethyltransferase activity
trna (guanine(27)-n2)-dimethyltransferase activity
guanosine(27) in tRNA(Tyr) + 2 S-adenosyl-L-methionine = N(2)-dimethylguanosine(27) in tRNA(Tyr) + 2 S-adenosyl-L-homocysteine + 2 H(+)
guanosine(27) in trna(tyr) + 2 s-adenosyl-l-methionine = n(2)-dimethylguanosine(27) in trna(tyr) + 2 s-adenosyl-l-homocysteine + 2 h(+)
