Summary

Description
Dimethylates a single guanine residue at position 26 of most tRNAs using S-adenosyl-L-methionine as donor of the methyl groups.
Catalytic Activity
guanosine(26) in tRNA + 2 S-adenosyl-L-methionine = 2 H(+) + N(2)-dimethylguanosine(26) in tRNA + 2 S-adenosyl-L-homocysteine
Similarity
Belongs to the class I-like SAM-binding methyltransferase superfamily. Trm1 family.
Keywords
