Here, we report the crystal structure of RauA in complex with its substrate, a biosynthetic intermediate of aurachin RE. Clear electron density showed that the quinolone ring is oriented parallel to the porphyrin plane of the heme cofactor, while the farnesyl chain curls into a U-shape topology and is buried inside the solvent-inaccessible hydrophobic interior of RauA. The nearest atom from the heme iron is the quinolone nitrogen (4.3A), which is consistent with RauA catalyzing the N-hydroxylation of the quinolone ring to produce mature aurachin RE.
