    摘要: An improved process for purifying a polypeptide using a packing material for reversed phase high performance liquid chromatography is provided. A process for purifying a polypeptide characterized in that an aqueous solution containing polypeptide obtained by pre-treating a polypeptide produced by a wide variety of cells to a predetermined state is adjusted to a specific pH value, to remove impurities, and is then treated with a packing material for reversed phase high performance liquid chromatography.

    摘要: A purified enzyme-I is obtained that participates in C-terminal amidation by acting on a peptide C-terminal glycine adduct to form a peptide C-terminal .alpha.-hydroxyglycine adduct. The enzyme has an optimum pH of about 5 to 7, an optimum temperature of 25 to 40.degree. C. and a molecular weight of about 25 kDa or about 36 kDa, and metal ions and ascorbic acid act as a cofactor. A purified enzyme-II is obtained that participates in C-terminal amidation by acting on the peptide C-terminal .alpha.-hydroxyglycine adduct to produce a C-terminal amidated compound. The enzyme has an optimum pH of about 5 to 6, an optimum temperature of 15 to 35.degree. C. and a molecular weight of about 40 kDa or about 43 kDa. Enzyme-I does not act on the peptide C-terminal .alpha.-hydroxyglycine adduct and enzyme-II does not act on the peptide C-terminal glycine adduct. The enzymes may be purified from a biological material such as horse serum by affinity chromatography using a peptide C-terminal glycine adduct as a ligand. The enzymes may also be obtained from host cells transformed with a plasmid containing a cDNA coding for the enzymes. Assay of activity of the enzymes is carried out by measuring the C-terminal .alpha.-hydroxyglycine adduct or the C-terminal amidated compound that has been isolated such as by high performance liquid chromatography with the use of an acetonitrile-containing buffer.
