FunFam 4941: Sulfite reductase, beta subunit (Hemoprotein)

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
Assimilatory sulfite reductase (ferredoxin). [EC: 1.8.7.1]
Hydrogen sulfide + 6 oxidized ferredoxin [iron-sulfur] cluster + 3 H(2)O = sulfite + 6 reduced ferredoxin [iron-sulfur] cluster + 6 H(+).
  • The enzyme participates in sulfate assimilation.
  • While it is usually found in cyanobacteria, plants and algae, it has also been reported in bacteria (cf. EC 1.8.1.2).
  • Formerly EC 1.8.99.1.

Ferredoxin--nitrite reductase. [EC: 1.7.7.1]
NH(3) + 2 H(2)O + 6 oxidized ferredoxin = nitrite + 6 reduced ferredoxin + 7 H(+).

    Nitrite reductase (NAD(P)H). [EC: 1.7.1.4]
    Ammonia + 3 NAD(P)(+) + 2 H(2)O = nitrite + 3 NAD(P)H.
    • The enzymes from the fungi Neurospora crassa, Emericella nidulans and Candida nitratophila and the bacterium Aliivibrio fischeri can use either NADPH or NADH as electron donor.
    • Cf. EC 1.7.1.15.
    • Formerly EC 1.6.6.4.
