FIG 7.

A model of possible functions of LytR-CpsA-Psr (LCP) proteins in B. anthracis. LCP proteins function to attach secondary cell wall polysaccharide (SCWP) to the peptidoglycan of B. anthracis cells. LcpB3 is the housekeeping LCP and attaches the majority of the SCWP. LcpB2, LcpC, and LcpD attach specialized SCWP to the cell poles and septa to enable proper deposition of S-layer and S-layer-associated proteins. LcpB1 and LcpB4 attach specialized SCWP along the midcell to allow for proper asymmetrical division during sporulation.
