FunFam 120583: 7-carboxy-7-deazaguanine synthase

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
7-carboxy-7-deazaguanine synthase. [EC: 4.3.99.3]
6-carboxy-5,6,7,8-tetrahydropterin = 7-carboxy-7-carbaguanine + NH(3).
  • The enzyme is a member of the superfamily of S-adenosyl-L-methionine- dependent radical (radical AdoMet) enzymes.
  • Binds a [4Fe-4S] cluster that is coordinated by 3 cysteines and an exchangeable S-adenosyl-L-methionine molecule.
  • The S-adenosyl-L-methionine is catalytic as it is regenerated at the end of the reaction.
  • The reaction is part of the biosynthesis pathway of queuosine.
