FunFam 163: S-adenosyl-L-methionine-dependent tRNA 4-demethylw...

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
TRNA 4-demethylwyosine synthase (AdoMet-dependent). [EC: 4.1.3.44]
N(1)-methylguanine(37) in tRNA(Phe) + pyruvate + S-adenosyl-L-methionine = 4-demethylwyosine(37) in tRNA(Phe) + L-methionine + 5'-deoxyadenosine + CO(2) + H(2)O.
  • This enzyme, which is a member of the superfamily of S-adenosyl-L- methionine-dependent radical (radical AdoMet) enzymes, binds two [4Fe-4S] clusters.
  • Carbons C(2) and C(3) from pyruvate are incorporated into 4-demethylwyosine.
  • The enzyme is found in eukaryotes where it is part of the pathway for wybutosine synthesis, and in archaea, where it is involved in the biosynthesis of archaeal wye bases, such as wyosine, isowyosine, and methylwyosine.
