EC 2.1.1.218 tRNA (adenine(9)-N(1))-methyltransferase. [-]    

Reaction: S-adenosyl-L-methionine + adenine(9) in tRNA = S-adenosyl-L-homocysteine + N(1)-methyladenine(9) in tRNA.
 


S-adenosyl-L-methionine
+ adenine(9) in tRNA
=
S-adenosyl-L-homocysteine
+ N(1)-methyladenine(9) in tRNA

Other name(s): tRNA m(1)A(9)-methyltransferase. tRNA(m(1)G(9)/m(1)A(9))-methyltransferase.
Comments: The enzyme from Sulfolobus acidocaldarius specifically methylates adenine(9) in tRNA. The bifunctional enzyme from Thermococcus kodakaraensis also catalyzes the methylation of guanine(9) in tRNA (cf. Ec 2.1.1.221). Formerly Ec 2.1.1.36.
