羧肽酶A，通常称为CPA1，是一种胰外肽酶，它水解C末端残基上带有芳香族或脂肪族侧链的肽键。 应用： 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。 Carboxypeptidase A, commonly called CPA1, is a pancreatic exopeptidase that hydrolyzes peptide bonds at the C-terminus residues with aromatic or aliphatic side chains. 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。
