Structural insights into sulfonamide degradation by a two-component flavin-dependent monooxygenase.

The sulfonamide-degrading monooxygenase sulX plays a dual role in bioremediation and antibiotic resistance, yet its molecular mechanism remains elusive. Here we report crystal structures of sulX in its ligand-free form, as an FMN-bound binary complex, and as ternary complexes with six distinct sulfonamides at resolutio...
