Outline of Final Research Achievements

Cell motility is powered by the actin ATPase through the cyclic polymerization and depolymerization-driven molecular movement-of actin. Our study has been aimed at understanding the mechanism how chemical energy release by the actin ATPase reaction is transformed into physical forces. In 2009, we discovered that polymerization is associated with conformational transition of actin from G-form to F-form. In the present study, we have elucidated first atomic resolution structures (at 1.5A resolution) of F-form actin. Based on these structures, we have proposed (1) mechanisms how the G-to-F transformation induces the ATP hydrolysis, (2) reasons why the Pi release from F-form actin is slow, and (3) reasons why ADP-F-actin is less stable than ATP-F-actin or ADPPi-F-actin. The present results have opened up a new era in our understanding how the ATP hydrolysis is coupled to the process of molecular assembly-disassembly (polymerization and depolymerization) of actin.
