Outline of Final Research Achievements

The protein translocation across the membrane is one of the fundamental, conserved reactions in all cells. SecDF, a proton driven motor, drives the protein translocation. SecDF has transmembrane helixes and soluble domains. Although the soluble region was shown to be highly mobile, the details were not clear. In this study, we have determined the crystal structures of SecDF that are different from the previous report. the data and the subsequent functional analyses, we propose a functional model of SecDF.
