Crystal structure analyses of the monooxygenase TetX in complex with tigecycline and minocycline support the observation that all clinically available tetracycline antibiotics can be inactivated by enzymatic hydroxylation. Molecular-dynamics simulations of dioxygen diffusion and experimental xenon-binding sites in TetX are compared with respect to putative dioxygen-binding cavities and dioxygen-diffusion pathways.
