Staphylococcal protein A (SpA) and the crystal structures of C and B–B domains. (a) Schematic showing the organization of SpA and its five protein-binding domains. The conserved linker (green) between E and D domains has a three-residue insertion, indicated by a star. (b) The asymmetric unit of C domain (cyan). The three helices are labeled (Hlx1–3) and the conserved linker regions are indicated (arrow) and colored dark blue. (c) The asymmetric unit of B–B domain. The two copies of B–B domain are colored in shades of green or purple. Each domain (Domain1 and Domain2) and the linker in between is depicted as a ribbon drawing, where Domain2 is rotated by 180°.
