Comments
  • FUNCTION: Dimethylates a single guanine residue at position 26 of a number of tRNAs using S-adenosyl-L-methionine as donor of the methyl groups (By similarity).
  • CATALYTIC ACTIVITY: S-adenosyl-L-methionine + tRNA = S-adenosyl-L-homocysteine + tRNA containing N2-methylguanine.
  • SIMILARITY: Belongs to the TRM1 family.
