一般描述
牛胰 α-糜蛋白酶 (BPC) 可催化 Povarov 反应制备四氢喹啉衍生物。牛胰 α-糜蛋白酶 (CHT) 是一种酶蛋白。已报道乙醇、1,4-二恶烷和乙腈等不同浓度的有机溶剂对 CHT 的影响。
胰凝乳蛋白酶(Chy)是一种丝氨酸蛋白酶。它的分子量为25.7kDa，广泛应用于医药行业。它由胰凝乳蛋白酶原合成，这种转化过程需要钙。
应用
牛胰 α-糜蛋白酶有以下用途：
- 通过质谱法 (MS) 鉴定蛋白质
- 肌球蛋白重链的分离与鉴定
- 毒素制剂
- 用于 SDS-PAGE 分析细胞蛋白的感染和未感染细胞孵育
生化/生理作用
α-牛胰腺胰凝乳蛋白酶通过Ca2+实现稳定并且催化肽键的水解，尤其氨基酸酪氨酸、苯基丙氨酸、色氨酸以及C端亮氨酸。α-胰凝乳蛋白酶受Cu2+和Hg的抑制。
一种丝氨酸蛋白酶，能将与芳香烃或其他大型疏水性侧链（Tyr、Trp、Phe、Met、Leu）结合的肽从键的羧基端水解。
单位定义
在 pH 7.8、25°C 条件下，1 个单位将每分钟水解 1.0 μmol BTEE。
