FunFam 3352: S-adenosylmethionine:tRNA ribosyltransferase-isome...

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
S-adenosylmethionine:tRNA ribosyltransferase-isomerase. [EC:]
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.
