Enzyme Commission Primary Name: tRNA (cytidine32/uridine32-2′-O)-methyltransferase
Enzyme Commission Synonyms: YfhQ, tRNA:Cm32/Um32 methyltransferase, TrMet(Xm32), TrmJ
Enzyme Commission Summary:
In Escherichia coli YfhQ is the only methyltransferase responsible for the formation of 2'-O-methylcytidine32 in tRNA. No methylation of cytosine34 in tRNALeu(CAA). In vitro the enzyme 2'-O-methylates cytidine34 of tRNASer1 and uridine32 of tRNAGln2.
