Functional Families

Overview of the Structural Clusters (SC) and Functional Families within this CATH Superfamily. Clusters with a representative structure are represented by a filled circle.

Superfamily EC Annotations

Note: the EC figure is not being displayed for this superfamily as there are more than 100 different EC terms.

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
Sulfhydrogenase. [EC: 1.12.98.4]
H(2) + polysulfide(n) = hydrogen sulfide + polysulfide(n-1).
  • The enzyme from the hyperthermophilic archaeon Pyrococcus furiosus is part of two heterotetrameric complexes where the beta and gamma subunits function as sulfur reductase and the alpha and delta subunits function as hydrogenases (EC 1.12.1.3 and EC 1.12.1.4).
  • Sulfur can also be used as substrate, but since it is insoluble in aqueous solution and polysulfide is generated abiotically by the reaction of hydrogen sulfide and sulfur, polysulfide is believed to be the true substrate.
  • Formerly EC 1.97.1.3.
