CAS Registry Number
Comments The enzyme from Sulfolobus acidocaldarius specifically methylates adenine9 in tRNA [1]. The bifunctional enzyme from Thermococcus kodakaraensis also catalyses the methylation of guanine9 in tRNA (cf. EC 2.1.1.221, tRNA (guanine9-N1)-methyltransferase).
Cofactor
History
Reactions S-adenosyl-L-methionine + adenine(9) in tRNA = S-adenosyl-L-homocysteine + N(1)-methyladenine(9) in tRNA.
