Enterotoxin type B Protein, S. aureus, Recombinant (GST)

Staphylococcal enterotoxin that activates the host immune system by binding as unprocessed molecules to major histocompatibility (MHC) complex class II and T-cell receptor (TCR) molecules. In turn, this ternary complex activates a large number of T-lymphocytes initiating a systemic release of proinflammatory cytokines. Causes also the intoxication staphylococcal food poisoning syndrome. Enterotoxin type B Protein, S. aureus, Recombinant (GST) is expressed in E. coli expression system with N-GST tag. The predicted molecular weight is 55.4 kDa and the accession number is P01552.
