FunFam 11: Formate dehydrogenase, alpha subunit

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
Formate dehydrogenase. [EC: 1.17.1.9]
Formate + NAD(+) = CO(2) + NADH.
  • The enzyme from most aerobic organisms is devoid of redox-active centers but that from the proteobacterium Methylosinus trichosporium contains iron-sulfur centers, flavin and a molybdenum center.
  • Together with EC 1.12.1.2, forms a system previously known as formate hydrogenlyase.
  • Formerly EC 1.2.1.2.

Formate dehydrogenase (acceptor). [EC: 1.17.99.7]
Formate + acceptor = CO(2) + reduced acceptor.
  • Formate dehydrogenase H is a cytoplasmic enzyme that oxidizes formate without oxygen transfer, transferring electrons to a hydrogenase.
  • The two enzymes form the formate-hydrogen lyase complex.
  • The enzyme contains a selenocysteine residue.
  • Formerly EC 1.1.99.33.
