What is the name of the enzyme that attaches each of the following to the peptidoglycan: (a) the polyglutamate chain in B. anthracis; (b) the pilus in Streptococcus pyogenes; and (c) InlA in L. monocytogenes? (3)
a. γ‐glutamyltranspeptidase- catalyzes the transfer of the glutamyl moiety to peptidoglycan.
b. Sortase crosslinks individual pilin monomers and ultimately joins the resulting covalent polymer to the cell-wall peptidoglycan in S. pyrogens.
c. InlA (Internalin) harbors an LPTTG motif and is anchored covalently by the sortase SrtA to meso-diaminopimelic acid residues of the peptidoglycan
