特異性
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。
應用
来自sigma的该酶已用于优化大鼠心脏均质化心室组织中所有线粒体群的释放。它还用于福尔马林固定石蜡包埋肝脏样本的预杂交处理，用于人和病毒DNA的检测。
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。 产品P8038，也被称为枯草杆菌蛋白酶Carlsberg，已用于水解心肌细胞以研究心脏线粒体NHE1的沉默。
生化／生理作用
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。
物理性質
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。
單位定義
在pH 7.5，37 °C 条件下，一单位的酶每分钟将会水解酪蛋白以产生与1.0 μ摩尔 (181 μg) 酪氨酸等同的颜色（Folin-Ciocalteu试剂提供的颜色）。
分析報告
氨基酸分析和等电聚焦电泳与枯草杆菌蛋白酶Carlsberg一致。

Exercise provides cardioprotection against ischemia-reperfusion injury, a process involving mitochondrial reactive oxygen species (ROS) generation and calcium overload. This study tested the hypotheses that isolated mitochondria from hearts of endurance-trained rats have decreased ROS production and improved tolerance against Ca(2+)-induced

Inhibition of Na(+)/H(+) exchanger 1 (NHE1) reduces cardiac ischemia-reperfusion (I/R) injury and also cardiac hypertrophy and failure. Although the mechanisms underlying these NHE1-mediated effects suggest delay of mitochondrial permeability transition pore (MPTP) opening, and reduction of mitochondrial-derived superoxide production, the
