Fig 1 — (A) WTA linkage unit and polymer. The linkage unit is attached to the peptidoglycan via the C6-hydroxyl of N-acetylmuramic acid and is composed of a GlcNAc (TagO-catalyzed), ManNAc (TagA-catalyzed), and n = 2–3 glycerol phosphates (TagB- and TagF-catalyzed). R = glycerol or ribitol, m = 40–60. (B) Cartoon ribbon representation of TagA^ΔC from T. italicus. Apo-TagA^ΔC crystallizes as a dimer. The dimer interface is over 1000 Å in surface area and is formed by buried hydrophobic residues. (C) TagA^ΔC protomer with secondary structural elements indicated. H = alpha helix, β = beta strand. (D) Electrostatic surface representation of the TagA^ΔC dimer. Negatively charged (red), neutral (white), and positively charged (blue) residues are indicated. Rotation of 180° about the dimer interface allows visualization of the pore.
