Superfamily Butyryl-CoA Dehydrogenase, subunit A, domain 3
Functional Family Cytochrome c-552

Enzyme Information

1.7.2.2
Nitrite reductase (cytochrome; ammonia-forming).
based on mapping to UniProt L0DSL2
NH(3) + 2 H(2)O + 6 ferricytochrome c = nitrite + 6 ferrocytochrome c + 7 H(+).
-!- The enzyme also reduces nitric oxide and hydroxylamine to ammonia, and sulfite to sulfide.
