FunFam 69318: tRNA-2-methylthio-N(6)-dimethylallyladenosine synt...

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-2-methylthio-N(6)-dimethylallyladenosine synthase. [EC: 2.8.4.3]
N(6)-dimethylallyladenine(37) in tRNA + sulfur-(sulfur carrier) + 2 S-adenosyl-L-methionine + reduced electron acceptor = 2-methylthio- N(6)-dimethylallyladenine(37) in tRNA + S-adenosyl-L-homocysteine + (sulfur carrier) + L-methionine + 5'-deoxyadenosine + electron acceptor.
  • This bacterial enzyme binds two [4Fe-4S] clusters as well as the transferred sulfur.
  • The enzyme is a member of the superfamily of S-adenosyl-L-methionine- dependent radical (radical AdoMet) enzymes.
  • The sulfur donor is believed to be one of the [4Fe-4S] clusters, which is sacrificed in the process, so that in vitro the reaction is a single turnover.
  • The identity of the electron donor is not known.
