Antimicrobial peptides and methods of use

摘要

Novel antimicrobial peptides from bovine and murine neutrophils are provided. The peptides, designated bovine granulocyte peptide A (BGP-A) and murine granulocyte peptide A (MGP-A) were purified to homogeneity from peripheral blood granulocytes. The amino acid and nucleotide sequence of BGP-A and MGP-A are also provided. A synthetic version of BGP-A and MGP-A is also provided. The purified BGP-A peptide is shown to have antimicrobial activity indistinguishable from that of natural BGP-A. Synthetic carboxamidated analogs of BGP-A (BGP-A-amide) and MGP-A (MGP-A-amide) are also provided.
