Transpeptidase that anchors surface proteins to the cell wall. Recognizes and modifies its substrate by proteolytic cleavage of a C-terminal sorting signal. Following cleavage, a covalent intermediate is formed via a thioester bond between the sortase and its substrate, which is then transferred and covalently attached to the cell wall. This sortase recognizes a Leu-Pro-x-Thr-Gly (LPXTG) motif, which is cleaved by the sortase between the threonine and glycine residues. Utilizes lipid II as the peptidoglycan substrate for the sorting reaction. Responsible for the display of important virulence factors. Important for interactions with the host and host colonization during infection. Source: Recombinant protein corresponding to aa25-206 from Staphylococcus aureus Sortase A, fused to 6X His-Tag at N-terminal, expressed in E.coli.
