| 生化机理 | 阿朴汀是一种竞争性丝氨酸蛋白酶抑制剂,能与酶的活性位点形成稳定的复合物并阻断酶的活性位点。这种结合是可逆的,大多数阿普罗汀-蛋白酶复合物会在 pH 值大于 10 或小于 3 的极端条件下解离。从结构上看,Aprotinin 是一种源自牛肺的单体球状蛋白质,由 58 个氨基酸组成,排列成一条具有三个交联二硫桥的多肽链。可逆性结合并阻断酶的活性位点。可抑制一系列丝氨酸蛋白酶,包括胰蛋白酶、糜蛋白酶、胰凝乳蛋白酶和凝血酶。广泛用作蛋白质纯化工具,以防止蛋白酶的产生。 |
| 产品介绍 |
Aprotinin is a single chain polypeptide (58 amino-acids) crosslinked by three disulfide bridges, showing competitive and reversible inhibiton of proteolytic and esterolytic activity. Aprotinin forms stable complexes and blocks the active sites of serine protease enzymes. Binding is reversible with most aprotinin-protease complexes dissociating at pH >10 or < 3 (optimum pH 5-7); effective concentration is equimolar with protease. Used as a proteolytic inhibitor in radioimmunoassays of polypeptide hormones.Aprotinin is largely used as an inhibitor of trypsin.
