SecDF shows 12 transmembrane (TM) regions and 6 periplasmic regions (P1-P6). This entry represents the N-terminal region of the base subdomain of the P1 domain that is located in the N- terminal half of the polypeptide, also known as SecD region. This domain folds into a a pseudo-symmetrical anti-parallel beta-sheet that rearranges to a beta-barrel architecture during ion transport. This domain, which covers the TM region [1-4], is related to Pfam:PF03176 and usually appears associated with Pfam:PF07549 and Pfam:PF02355.

SecDF f ...This entry represents the head subdomain from P1 domain from SecDF proteins, which constitutes a critical element for proton transport [1-3]. P1 domain P1 binds an unfolded protein, and undergoes functionally important conformational changes. SecDF functions as a membrane-integrated chaperone that mediates ATP-independent protein translocation.
