Enzyme Information
| 1.14.13.39 |
Nitric-oxide synthase (NADPH).
based on mapping to UniProt P29475
2 L-arginine + 3 NADPH + 4 O(2) = 2 L-citrulline + 2 nitric oxide + 3 NADP(+) + 4 H(2)O.
-!- This eukaryotic enzyme, which is found in plants and animals, consists of oxygenase and reductase domains that are linked via a regulatory calmodulin-binding domain. -!- Upon calcium-induced calmodulin binding, the reductase and oxygenase domains form a complex, allowing electrons to flow from NADPH via FAD and FMN to the active center. -!- May produce superoxide under certain conditions. -!- Cf. EC 1.14.13.165.
