ActVA-Orf6 monooxygenase from Streptomyces coelicolor that catalyses the, oxidation of an aromatic intermediate of the actinorhodin biosynthetic, pathway is a member of a class of small monooxygenases that carry out, oxygenation without the assistance of any of the prosthetic groups, metal, ions or cofactors normally associated with activation of molecular oxygen., The overall structure is a ferredoxin-like fold with a novel dimeric, assembly, indicating that the widely represented ferredoxin fold may, sustain yet another functionality. The resolution (1.3 A) of the enzyme, structure and its complex with substrate and product analogues allows us, to visualize the mechanism of binding and activation of the substrate for, attack by molecular oxygen, and utilization of two gates for the reaction, components including a proton gate and an O(2)/H(2)O gate with a putative, protein channel. This is the first crystal structure of an enzyme involved, in the tailoring of a type II aromatic polyketide and illustrates some of, the enzyme-substrate recognition features that may apply to a range of, other enzymes involved in modifying a polyketide core structure.
