This domain is found in the putative N-acetylmuramoyl-L-alanine amidase cwp6 from Clostridioides difficile and similar proteins from firmicutes. Cwp6, which is involved in cell wall remodelling, consists of five domains: an N-terminal (this entry), a trimer of CWB2 (Pfam:PF04122) and a C-terminal (Pfam:PF01520). This domain, which locates at the bottom of the molecule, folds into a seven-stranded beta-barrel with one alpha-helix and with two additional short beta-strands [1].	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
