Comment | The CsaB protein (cell surface anchoring B) of Bacillus anthracis adds a pyruvoyl group to peptidoglycan-associated polysaccharide. This addition is required for proteins with an S-layer homology domain (PF00395) to bind. Within the larger group of proteins described by Pfam model PF04230, this model represents a distinct clade that nearly exactly follows the phylogenetic distribution of the S-layer homology domain (PF00395). |
