Staphopain B is a cysteine protease that severely disrupts host immunity by degrading elastin, fibrin, fibronectin, and kininogen. It blocks phagocytosis of opsonized Staphylococcus aureus and induces neutrophil and monocyte death through proteolytic activity. Staphopain B Protein, S. aureus (GST) is the recombinant Staphylococcus aureus-derived Staphopain B protein, expressed by E. coli , with N-GST labeled tag.
