An international team led by researchers at UCSF used protein crystallography at the Advanced Light Source (ALS) beamline 8.3.1 to obtain structures of several influenza antiviral drug molecules bound to their proton-channel targets in both open and closed conformations. These complexes provide the first high-resolution views of how the drugs interact with and disrupt the water-molecule networks lining the M2 transmembrane channel. The structures provide an atomic-level blueprint from which to design more effective anti-influenza drugs that can overcome growing drug resistance. ALS beamline 8.3.1 is operated by James Holton, MBIB beamline scientist and associate adjunct professor at UCSF.
