This OB-fold domain folds into a five-stranded beta-barrel [1]. Members of this family are found in various staphylococcal toxins described as staphylococcal superantigen-like (SSL) proteins that are related to the staphylococcal enterotoxins (SEs) or superantigens. These SSL proteins of which 11 have so far been characterised have a typical SE tertiary structure consisting of a distinct oligonucleotide/oligosaccharide binding (OB-fold), this domain, linked to a beta-grasp domain, family Stap_Strp_tox_C, Pfam:PF02876. SSLs do not bind to T-cell receptors or major histocompatibility complex class II molecules and do not stimulate T cells. SSLs target components of innate immunity, such as complement, Fc receptors, and myeloid cells 2,3,4,5,6,7,8]. SSL protein 7 (SSL7) is the best characterised of the SSLs and binds complement factor C5 and IgA with high affinity and inhibits the end stage of complement activation and IgA binding to FcalphaR [8].
