M. Scocchi et al., MOLECULAR-CLONING OF BAC7, A PROLINE-RICH AND ARGININE-RICH ANTIMICROBIAL PEPTIDE FROM BOVINE NEUTROPHILS, FEBS letters, 352(2), 1994, pp. 197-200
Bac7 is a 7 kDa proline- and arginine-rich antimicrobial peptide which
was purified from bovine neutrophils. We have used PCR to clone the c
DNA of Bac7 precursor, a polypeptide of 21,569 Da. This cDNA is highly
conserved in the 5' region, with respect to the corresponding region
in the precursors of several other structurally unrelated myeloid anti
microbial peptides. Furthermore, a 148 nt non-coding region at the 3'
end is 75% homologous to a corresponding region of the cDNA of the pre
cursor of PR-39, a porcine antibacterial peptide which is also proline
- and arginine-rich.
