This entry represents the third domain (D3) of cell wall protein Cwp8 found in C. difficile. This domain folds into an alpha/beta structure consisting of a four-stranded antiparallel beta-sheet packed on one side with alpha-helices [1]. This domain is related to domain 1 (D1) of the cell wall protein Cwp2 from the same organism.	Domain

This domain is found in 1 to 3 tandem copies in a wide variety of bacterial cell surface proteins. It has been show the three tandem repeats of the CWB2 domain are essential for correct anchoring to the cell wall [1]. It was shown that in SlpA and Cwp2 that these domains were essential for the binding of PSII an anionic teichoic acid-like component of the cell wall [1]. The structure of the Cwp8 and Cwp6 proteins shows that this domain forms a trimeric arrangement with each domain adopting a structure with some similarity to the Toprim fold [2]. A groove containing many conserved residues was predicted to be the site of the PSII molecule [2].	Domain

Cwp8 is a member of the C. difficile cell wall protein (CWP) family. It consists of several domains. This entry represents the domain 2 that is a part of the N-terminal elongated part of the molecule [1]. This domain is composed of a three-stranded antiparallel beta-sheet, an alpha-helix packed on it and a short beta-hairpin located at the edge of the sheet.	Domain
