Novel peptide having elastase inhibitor activity and process for producing the same

摘要

A novel peptide having an elastase inhibitor activity and being useful as a remedy or preventive for diseases caused by elastase is produced by partially modifying the constitutive amino acid of HI-8 present on the C-terminal side of a human urine trypsin inhibitor and having a trypsin inhibitor activity. The invention also provides a gene coding for the peptide, a plasmid containing the gene, a recombinant microbe holding the plasmid, and a process for producing the peptide by using the recombinant microbe.
