1P163 The response of TF1 βE190D mutant to the external torque(11. Molecular motor,Poster,The 52nd Annual Meeting of the Biophysical Society of Japan(BSJ2014))
Abstract:F1-ATPase is a motor protein driven by ATP hydrolysis. It converts chemical free energy change into the kinetic energy of the rotation. Toyabe examined the external torque dependency of the rotation rate of wild type F1-ATPase (PANS 2011). He found the maximum work estimated from stall torque is nearly equal to the free energy change of ATP hydrolysis, reached conclusion of high energy efficiency. Thus, interest issue is to find out the mechanism of this high efficiency. In the previous annual meeting, we repo… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
