The crystal structure of staphylococcal enterotoxin H : Implications for binding properties to MHC class II and TcR molecules
The X-ray structure of the superantigen staphylococcal enterotoxin H (SEH) has been determined at 1.69 Å resolution. In this paper we present two structures of zinc-free SEH (apoSEH) and one zinc-loaded form of SEH (ZnSEH). SEH exhibits the conventional superantigen (SAg) fold with two characteristic domains. In ZnSEH one zinc ion per SEH molecule is bound to the C-terminal β-sheet in the region i
