  Purified enzymatic compositions are provided having alpha-amidating enzymes capable of catalyzing the conversion of a peptidyl compound having a C-terminal glycine residue to a corresponding peptidyl amide having an amino group in place of the C-terminal glycine. The purified compositions have specific activities above 25mU per mg protein and are sufficiently free of proteases to allow effective catalysis of even peptidyl compounds having L-amino acids. Biologically important alpha-amidated products such as calcitonin and other regulatory hormones are efficiently produced using the alpha-amidation reaction catalyzed by the enzymes. Purification by size exclusion chromatography in combination with strong anion exchange chromatography results in homogeneous enzyme species which are used to prepare antibodies specific for the alpha-amidating enzyme. A gene capable of expressing the alpha-amidating enzyme is ligated into an expression vector and transformed into a host cell capable of expressing the gene.

  所提供的纯化酶组合物具有α-酰胺化酶，能够催化具有 C-末端甘氨酸残基的肽基化合物转化为相应的肽基酰胺，肽基酰胺具有取代 C-末端甘氨酸的氨基。纯化组合物的比活性高于每毫克蛋白质 25mU 的水平，并且不含蛋白酶，甚至可以有效催化具有 L-氨基酸的肽化合物。利用该酶催化的α-酰胺化反应，可有效生产出具有重要生物学意义的α-酰胺化产品，如降钙素和其他调节激素。通过尺寸排阻色谱法结合强阴离子交换色谱法进行纯化，可得到均一的酶种类，用于制备针对α-酰胺化酶的特异性抗体。将能够表达α-酰胺化酶的基因连接到表达载体中，并转化到能够表达该基因的宿主细胞中。
