Modular architecture of the Y. pseudotuberculosis invasin. (A) A schematic topology model of preprotein. From N-terminus: (SP) signal peptide, (a) periplasmic hydrophilic α-domain, (β-barrel) OM embedded β-barrel domain, (α') periplasmic hydrophilic α'-domain, (D1–D4) extracellular Ig-like domains, (D5) extracellular distal domain of the C-type lectin-like fold. D4 and D5 form a functional integrin binding module. (B) Ribbon diagram of the structure of D1–D5 (1CWV). Residues D811, R883, C907, D911, and C982 (space-filling representation) are implicated in integrin binding. (C) Ribbon diagram of the β-barrel structure (4E1T).
