NbtG is unable to stabilize the FADOOH intermediate, which results in production of hydrogen peroxide and superoxide. NbtG is also active on D-Lys, although it binds L-Lys with a higher affinity. NbtG can use both NADH and NADPH and is highly uncoupled, producing more superoxide and hydrogen peroxide than hydroxylated Lys. NbtG is highly active in the absence of L-Lys, having about 2fold higher activity with NADPH as compared with NADH. Under these conditions, NbtG functions as an oxidase, as no hydroxylation occurs, overview

the flavoenzyme catalyzes the NADPH-and oxygen-dependent hydroxylation of lysine, NbtG utilizes NADPH and molecular oxygen to hydroxylate the Nepsilon-atom of L-Lys. NbtG is unable to stabilize the FADOOH intermediate, which results in production of hydrogen peroxide and superoxide. The biosynthesis of the siderophore nocobactin in Nocardia farcinica requires functioning of NbtG

construction of recombinant IucD proteins with modified amino termini by creating three in-frame gene fusions of IucD to the amino-terminal amino acids of the cytoplasmic enzyme beta-galactosidase. Two of these constructs result in the addition of the iucD coding region of a hydrophilic leader sequence of 13 and 30 amino acids. The other construct involves the deletion of the first 47 amino acids of the IucD amino terminus and the addition of 19 amino acids of the amino terminus of beta-galactosidase. Cells expressing any of the three recombinant IucD forms produce soluble N6-hydroxylysine
