(a.) Overlay of PhqK cocrystal structures. The structures are complexed with 14 (green) and 15 (teal). (b.) The β€œin” FAD cofactor was modeled from the HpxO structure (PDB: 3rp7) into the PhqK cocrystal structure with 15, where the FAD-C4a is perfectly aligned to perform the epoxidation of the indole C2=C3.
