L-lysine 6-monooxygenase (NADPH) (EC 1.14.13.59) is an enzyme that catalyzes the chemical reaction
The four substrates of this enzyme are L-lysine, reduced nicotinamide adenine dinucleotide phosphate (NADPH), oxygen, and a proton. Its products are N(6)-hydroxy-L-lysine, oxidised NADP+, and water. The enzyme is a flavin-containing monooxygenase that uses molecular oxygen as oxidant and incorporates one of its atoms into the starting material. The systematic name of this enzyme class is L-lysine,NADPH:oxygen oxidoreductase (6-hydroxylating). It is also called lysine N6-hydroxylase. It participates in siderophore biosynthesis and uses flavin adenine dinucleotide as a cofactor.
