L-ornithine N(5)-monooxygenase; part of the siderophore basidioferrin biosynthetic pathway (PubMed:28842536). The biosynthesis of basidioferrin depends on the hydroxylation of ornithine to N(5)-hydroxyornithine, catalyzed by the monooxygenase SMO1 (PubMed:28842536). The second step, the acylation of N(5)-hydroxy-L-ornithine is catalyzed by a not yet identified N-acyltransferase (PubMed:22434909). Finally, assembly of basidioferrin is catalyzed by the nonribosomal peptide synthase (NRPS) NPS2 via amide bond formation between three L-AHO molecules to release the linear L-AHO trimer (PubMed:22434909). L-ornithine + NADPH + O2 = H2O + N(5)-hydroxy-L-ornithine + NADP(+) L-ornithine + NADH + O2 = H2O + N(5)-hydroxy-L-ornithine + NAD(+) Binds 1 FAD per subunit. Siderophore biosynthesis. Homotetramer. Expression is induced under iron-depleted conditions (PubMed:28842536). Belongs to the lysine N(6)-hydroxylase/L-ornithine N(5)-oxygenase family.
