This domain is found in Protein translocase subunit SecDF from Thermus thermophilus, which belongs to the RND superfamily. 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.	Domain
