TRNA (cytidine32/uridine32-2'-O)-methyltransferase (EC 2.1.1.200, YfhQ, tRNA:Cm32/Um32 methyltransferase, TrMet(Xm32), TrmJ) is an enzyme with systematic name S-adenosyl-L-methionine:tRNA (cytidine32/uridine32-2'-O)-methyltransferase.[1] This enzyme catalyses the following chemical reaction
- (1) S-adenosyl-L-methionine + cytidine32 in tRNA S-adenosyl-L-homocysteine + 2'-O-methylcytidine32 in tRNA
- (2) S-adenosyl-L-methionine + uridine32 in tRNA S-adenosyl-L-homocysteine + 2'-O-methyluridine32 in tRNA
In Escherichia coli YfhQ is the only methyltransferase responsible for the formation of 2'-O-methylcytidine32 in tRNA.
