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
Molybdenum cofactor guanylyltransferase. [EC: 2.7.7.77]
GTP + molybdenum cofactor = diphosphate + guanylyl molybdenum cofactor.
  • Catalyzes the guanylation of the molybdenum cofactor.
  • This modification occurs only in prokaryotes.

Molybdopterin molybdotransferase. [EC: 2.10.1.1]
Adenylyl-molybdopterin + molybdate = molybdenum cofactor + AMP.
  • Catalyzes the insertion of molybdenum into the ene-dithiol group of molybdopterin.
  • In eukaryotes this reaction is catalyzed by the N-terminal domain of a fusion protein whose C-terminal domain catalyzes EC 2.7.7.75.
