CATH Clusters

Superfamily Nucleotide-binding domain of ferredoxin-NADP reductase (FNR) module
Functional Family Flavohemoprotein

Enzyme Information

1.14.12.17
Nitric oxide dioxygenase.
based on mapping to UniProt P24232
2 nitric oxide + 2 O(2) + NAD(P)H = 2 nitrate + NAD(P)(+) + H(+).
-!- It has been proposed that FAD functions as the electron carrier from NADPH to the ferric heme prosthetic group.
