Enzyme Information

2.4.99.17
S-adenosylmethionine:tRNA ribosyltransferase-isomerase.
based on mapping to UniProt Q9WZ44
S-adenosyl-L-methionine + 7-aminomethyl-7-carbaguanosine(34) in tRNA = L-methionine + adenine + epoxyqueuosine(34) in tRNA.
-!- The reaction is a combined transfer and isomerization of the ribose moiety of S-adenosyl-L-methionine to the modified guanosine base in the wobble position in tRNAs specific for Tyr, His, Asp or Asn. -!- It is part of the queuosine biosynthesis pathway.
