Proteus mirabilis, citrobacter intermedius, staphylococcus aureus haemolyticus and staphylococcus albus produce extracellualr proteinases with maximum activity at pH 7.8. These proteinases are inhibited practically completely by human and animal blood serum. This inhibitory activity of human serum is caused by alpha2-macroglobulin. Ovomucoid showed nearly the same inhibitory activity as alpha2-macroglobulin.
奇异变形杆菌、中间柠檬酸杆菌、溶血葡萄球菌和白色葡萄球菌可产生细胞外蛋白酶,其在pH 7.8时活性最强。这些蛋白酶几乎完全被人和动物血清所抑制。人血清的这种抑制活性是由α2-巨球蛋白引起的。卵类粘蛋白显示出与α2-巨球蛋白几乎相同的抑制活性。
