摘要: A precursor of a C-terminal amidated peptide represented by the general formula P-X-Gly-Y.sub.n, wherein P is a peptide residue. X is an amino acid residue the C terminal of which (on the Gly side) can be converted in vivo to a --CONH.sub.2 group. Gly is a glycine residue, Y is a basic amino acid residue, n is an interger of 2 to 4 and a further amino acid residue other than Y or a peptide residue may be attached to Y.sub.n, is produced by a gene engineering technology. The precursor exhibits in vivo physiological activity like the C-terminal amidated peptide.
