Welcome to the Murakami Lab at Penn State University
Our research interests are centered on understanding the mechanism of gene expression by the enzyme RNA polymerase. We apply X-ray crystallography and cryo-electron microscopy techniques to reveal three-dimensional structures of bacterial, archaeal and bacteriophage RNA polymerases for elucidating the mechanism of RNA transcription and its regulation.
