Protein Family Models

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]. [1]. 25649385.
