Abstract:

The project will study the structure and mechanism of drug efflux pumps from bacteria that are driven by ATP hydrolysis. The pumps are three-component assemblies, and protocols have been established in our laboratory to prepare stable specimens that are suitable for structure analysis by cryo-electron microscopy and X-ray crystallography and functional analysis in reconstituted transport assays.
