Abstact

AlpK is an essential monooxygenase involved in the biosynthesis of kinamycin. It catalyzes the C5-hyfroxylattion of the crucial benzo[b]-fluorence intermediate in kinamycin synthesis. However, the structure and mechanism of AlpK is unclear. Here, we report the first structure of AlpK in complex with FAD. Our structure sheds light on the catalytic mechanism of AlpK.
