L-ornithine,NAD(P)H:oxygen oxidoreductase (N5-hydroxylating)
A flavoprotein (FAD). The enzyme from the pathogenic fungus Aspergillus fumigatus catalyses a step in the biosynthesis of the siderophores triacetylfusarinine and desferriferricrocin, while the enzyme from the bacterium Kutzneria sp. 744 is involved in the biosynthesis of piperazate, a building block of the kutzneride family of antifungal antibiotics. Activity of the fungal enzyme is higher with NADPH, due to the fact that following the reduction of the flavin, NADP+ (but not NAD+) stabilizes the C4a-hydroperoxyflavin intermediate that oxidizes the substrate [3]. cf. EC 1.14.13.195, L-ornithine N5-monooxygenase (NADPH).
