Protein attributes

Sequence length	431 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Flavoprotein monooxygenase required for N-hydroxylation of the two acylated lysine residues during mycobactin assembly, thus producing the hydroxamate groups necessary for iron sequestration. Is also able, but less efficiently, to hydroxylate L-lysine (non acylated) in vitro By similarity.
Catalytic activity	L-lysine + NADPH + O2 = N(6)-hydroxy-L-lysine + NADP+ + H2O.
Cofactor	FAD By similarity.
Pathway	Siderophore biosynthesis; mycobactin biosynthesis.
Sequence similarities	Belongs to the lysine N(6)-hydroxylase/L-ornithine N(5)-oxygenase family.
