FunFam 5:

Please note: GO 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.

There are 5 GO terms relating to "molecular function"

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.
GO Term Annotations Evidence
Sulfite reductase activity GO:0016002
Catalysis of the reaction: hydrogen sulfide + acceptor + 3 H2O = sulfite + reduced acceptor.
1 Q7MSJ8 (/IDA)
Oxidoreductase activity, acting on a sulfur group of donors GO:0016667
Catalysis of an oxidation-reduction (redox) reaction in which a sulfur-containing group acts as a hydrogen or electron donor and reduces a hydrogen or electron acceptor.
1 Q7MSJ8 (/IDA)
