羧肽酶 A 来源于牛胰腺

C755281-5KU

5KU

(Type II-PMSF treated),≥20 units/mg protein

来自牛胰腺的羧肽酶A已被用于体外模拟消化。来自牛胰腺的羧肽酶A已被用于研究大肠杆菌中可溶性和可活化形式的牛羧肽酶原A的表达。来自牛胰腺的羧肽酶A也已被用于研究鸵鸟羧肽酶的前体形式的分离和部分表征。应用： 羧肽酶A（CPA）是在肥大细胞活化后释放的一种分泌蛋白酶，可促进急性过敏反应。与其他分泌的蛋白酶相比，羧肽酶A在体内具有更长的半衰期。 Carboxypeptidase A (CPA) is a secreted protease is liberated after the activation of mast cells to facilitate acute anaphylaxis. Carboxypeptidase A has a long half-life in vivo , when compared to other secreted proteases. Application: Carboxypeptidase A from bovine pancreas has been used in in vitro simulated digestion. Carboxypeptidase A from bovine pancreas has been used in a study to investigate the expression of a soluble and activatable form of bovine procarboxypeptidase A in Escherichia coli. Carboxypeptidase A from bovine pancreas has also been used in a study to investigate the isolation and partial characterization of precursor forms of ostrich carboxypeptidase.

从牛胰腺分离的羧肽酶是一种金属酶，每摩尔蛋白含有1克原子锌。 它可催化肽和蛋白质中羧基末端肽键的水解。它主要对芳香族和疏水性侧链具有特异性，例如苯丙氨酸、色氨酸或亮氨酸。该酶还表现出酯酶活性。它可被β-苯基丙酸酯和吲哚乙酸酯抑制。†
