Reaction: S-adenosyl-L-methionine + guanine10 in tRNA = S-adenosyl-L-homocysteine + N2-methylguanine10 in tRNA
Other name(s): (m2G10) methyltransferase; Trm11-Trm112 complex
Systematic name: S-adenosyl-L-methionine:tRNA (guanine10-N2)-methyltransferase
Comments: In contrast to the archaeal enzyme tRNA (guanine10-N2)-dimethyltransferase (EC 184.108.40.206), tRNA (guanine10-N2)-methyltransferase from yeast does not catalyse the methylation from N2-methylguanine10 to N2-dimethylguanine10 in tRNA.
