Comparison of amino acid sequence data suggested that there may be a functional relationship between the staphylococcal epidermolytic toxins and V8 proteinase. The hypothesis was tested by treating epidermolytic toxin with di-isopropyl phosphorofluoridate, which bound specifically at serine-195, the homologue of the active-site serine residue of V8 proteinase.
氨基酸序列数据的比较表明,葡萄球菌表皮溶解毒素与V8蛋白酶之间可能存在功能关系。通过用二异丙基氟磷酸酯处理表皮溶解毒素来验证这一假设,二异丙基氟磷酸酯特异性结合在丝氨酸-195处,该位点是V8蛋白酶活性位点丝氨酸残基的同源物。
