IUBMB Enzyme Nomenclature

EC 2.1.1.205

Accepted name: tRNA (cytidine32/guanosine34-2'-O)-methyltransferase

Reaction: S-adenosyl-L-methionine + cytidine32/guanosine34 in tRNA = S-adenosyl-L-homocysteine + 2'-O-methylcytidine32/2'-O-methylguanosine34 in tRNA

Other name(s): Trm7p

Systematic name: S-adenosyl-L-methionine:tRNA (cytidine32/guanosine34-2'-O)-methyltransferase

Comments: The enzyme from Saccharomyces cerevisiae catalyses the formation of 2'-O-methylnucleotides at positions 32 and 34 of the yeast tRNAPhe, tRNATrp and, possibly, tRNALeu.
