Figure 1.
Structure of S. aureus PepG. The shaded area on the PepG monomer shows the minimal component that accounts for the ability of PepG to synergize with LTA (or IFN-γ) to induce NO formation in J774.2 macrophages. The points at which enzymes lyse PepG are identified by markers ( filled circle, mutanolysin or M1; open square, lysostaphin; filled triangle, SALE). Numbers, Amino acid position on the stem peptide.
