Characteristics of AgI/II proteins present in different streptococci. The leader peptide signal (LP), N-terminal domain (N-term), alanine-rich region (A), variable region (V), proline-rich region (P), and C-terminal domain, and the cell wall anchorage domain (CWA) containing the LPXTG domain are illustrated for the S. suis AgI/II, S. pyogenes AspA, S. mutans SpaP, and S. gordonii SspA and SspB. Amino acid (aa) size and percentage of S. suis AgI/II protein identity are also indicated. Black arrows indicate the location of primers pET151_S2agI/IIΔCWA_F and pET151_S2agI/II _ ΔLPXTG_R, which were used to produce the his-tagged recombinant AgI/II protein, rAgI/II.
