General description
枯草杆菌蛋白酶是一种具有27 KDa分子量并不含有二硫键的非糖基化单一多肽链。
Application
这是从地衣芽孢杆菌发酵中分离得到的蛋白水解酶。它是一种对天然和变性蛋白具有广泛特异性的丝氨酸内切蛋白酶，并在碱性条件下具有活性。它用于总膳食纤维检测（TDF-100A）中。
Biochem/physiol Actions
枯草杆菌蛋白酶A是丝氨酸S8内蛋白酶家族的一员。它具有宽泛的特异性并在P1位对大的未带点残基具有偏好性。它可水解天然和变性的蛋白，并在碱性条件下具有活性。
蛋白酶可通过肽键的水解使蛋白质分解代谢。 蛋白酶可被丝氨酸活性位点抑制剂所灭活，如苯甲基磺酰氟（PMSF）和二异丙基氟磷酸盐。
Other Notes
在pH 7.5、37°C条件下，一个单位每分钟可水解酪蛋白，生成相当于1.0 μmole (181 μg)酪氨酸的颜色。
