FunFam 39463: Formate dehydrogenase iron-sulfur subunit

There are 3 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: 1.2.1.2]
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.

Formate dehydrogenase (cytochrome). [EC: 1.2.2.1]
Formate + 2 ferricytochrome b1 = CO(2) + 2 ferrocytochrome b1 + 2 H(+).

    Formate dehydrogenase-N. [EC: 1.1.5.6]
    Formate + a quinone = CO(2) + a quinol.
    • Formate dehydrogenase-N oxidizes formate in the periplasm, transferring electrons via the menaquinone pool in the cytoplasmic membrane to a dissimilatory nitrate reductase (EC 1.7.5.1), which transfers electrons to nitrate in the cytoplasm.
    • The system generates proton motive force under anaerobic conditions.
