The ribosome is a 2.5 MDa RNA-based machine that translates the genetic code in all organisms. In the last decade, numerous structures of the ribosome and various ribosomal complexes have been solved by xray crystallography and cryo-electron microscopy. A primary challenge in the field today is to define the molecular mechanisms that underline protein synthesis in structural terms. To date, much of our effort has focused on translocation, the coupled movement of tRNA and mRNA in the ribosome, a reaction catalyzed by EF-G and GTP. Work from our group has provided insight regarding both the thermodynamics and kinetics of tRNA movement within the ribosome and the mode of action of several translocation inhibitors. While our studies on translocation will continue, we have expanded our efforts to investigate other steps in protein CURRICULUM VITAE KURT FREDRICK synthesis. Recently, we have isolated and begun to characterize a number of 16S rRNA mutations that confer specific defects in initiation, elongation, and/or termination.
