TRNA (guanine9-N1)-methyltransferase (EC 2.1.1.221, Trm10p, tRNA(m1G9/m1A9)-methyltransferase, tRNA(m1G9/m1A9)MTase, tRNA (guanine-N(1)-)-methyltransferase, tRNA m1G9-methyltransferase, tRNA m1G9 MTase) is an enzyme with systematic name S-adenosyl-L-methionine:tRNA (guanine9-N1)-methyltransferase.[1][2] This enzyme catalyses the following chemical reaction
- S-adenosyl-L-methionine + guanine9 in tRNA [math]\displaystyle{ \rightleftharpoons }[/math] S-adenosyl-L-homocysteine + N1-methylguanine9 in tRNA
The enzyme from Saccharomyces cerevisiae specifically methylates guanine9.
