Comments [?]

Function Catalyzes the 2'-O methylation of guanosine at position 18 in tRNA.
Catalytic activity RHEA:20077: guanosine(18) in tRNA + S-adenosyl-L-methionine = 2'-O-methylguanosine(18) in tRNA + H(+) + S-adenosyl-L-homocysteine
EC 2.1.1.34
Similarity Belongs to the class IV-like SAM-binding methyltransferase superfamily. RNA methyltransferase TrmH family.
