Identification
Name:tRNA 5-methylaminomethyl-2-thiouridine biosynthesis bifunctional protein mnmC
Synonyms:
  • tRNA mnm(5)s(2)U biosynthesis bifunctional protein
  • tRNA (mnm(5)s(2)U34)-methyltransferase
  • FAD-dependent cmnm(5)s(2)U34 oxidoreductase
Gene Name:mnmC
Enzyme Class:
Biological Properties
General Function:Involved in oxidoreductase activity
Specific Function:Catalyzes the last two steps in the biosynthesis of 5- methylaminomethyl-2-thiouridine (mnm(5)s(2)U) at the wobble position (U34) in tRNA. Catalyzes the FAD-dependent demodification of cmnm(5)s(2)U34 to nm(5)s(2)U34, followed by the transfer of a methyl group from S-adenosyl-L-methionine to nm(5)s(2)U34, to form mnm(5)s(2)U34
Cellular Location:Cytoplasm (Potential)
