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
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。
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。
Analysis Note
氨基酸分析和等电聚焦电泳与枯草杆菌蛋白酶Carlsberg一致。
Other Notes
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）。

The implementation of self-assembled biomolecules on solid materials, in particular, sensor and electrode surfaces, gains increasing importance for the design of stable functional platforms, bioinspired materials, and biosensors. The present study reports on the formation of a planar hybrid lipid/polymer

In the present investigation, bovine ovary prenatal development was studied using immunohistochemistry and laser-assisted microdissection (LAM). A major aim of this study was to evaluate the protein expression pattern of intermediate filaments (IF) and distinguish S100 protein (S100 alpha and

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

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
