Figure 3.

Representation of the structure of cell wall-anchored proteins from Streptococcus agalactiae. All cell wall-anchored S. agalactiae proteins contain a signal sequence (S) at the N-terminal end and a sorting signal (LPXTG) at the C-terminus. The signal sequences are removed during secretion across the cytoplasmic membrane. Each CWA protein is identified with a capital alphabetic letter (A–J). Domains involved in specific ligand binding are also shown. For further details see the text. Drawings of CWA protein here reported are those for which the domain organization and ligand binding sites have been defined.
