The name of this superfamily has been modified since the most recent official CATH+ release (v4_3_0). At the point of the last release, this superfamily was named:

"
Molybdopterin cofactor biosynthesis C (MoaC) domain

FunFam 2: Molybdenum cofactor biosynthesis protein 1

There are 2 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
GTP 3',8-cyclase. [EC: 4.1.99.22]
GTP + S-adenosyl-L-methionine + reduced electron acceptor = (8S)-3',8- cyclo-7,8-dihydroguanosine 5'-triphosphate + 5'-deoxyadenosine + L-methionine + oxidized electron acceptor.
  • The enzyme catalyzes an early step in the biosynthesis of the molybdenum cofactor (MoCo).
  • The enzyme belongs to the superfamily of radical S-adenosyl-L- methionine (radical SAM) enzymes.
  • Formerly EC 4.1.99.18.

Cyclic pyranopterin monophosphate synthase. [EC: 4.6.1.17]
(8S)-3',8-cyclo-7,8-dihydroguanosine 5'-triphosphate = cyclic pyranopterin phosphate + diphosphate.
  • The enzyme catalyzes an early step in the biosynthesis of the molybdenum cofactor (MoCo).
  • Formerly EC 4.1.99.18.
