Comments The enzyme from Saccharomyces cerevisiae specifically methylates guanine9 [1,2]. The bifunctional enzyme from Thermococcus kodakaraensis also catalyses the methylation of adenine9 in tRNA (cf. EC 2.1.1.218, tRNA (adenine9-N1)-methyltransferase) [1].
Cofactor
History
Reactions S-adenosyl-L-methionine + guanine(9) in tRNA = S-adenosyl-L-homocysteine + N(1)-methylguanine(9) in tRNA
