Isolation and characterization of four antibacterial peptides from bovine hemoglobin
چکیده انگلیسی

Peptic digestion of bovine hemoglobin at low degree of hydrolysis yields several intermediate peptide fractions after separation by reversed phase HPLC exhibiting antibacterial activity against Micrococcus luteus A270, Listeria innocua, Escherichia coli, and Salmonella enteritidis. From these fractions, four new antibacterial peptides were isolated and analyzed by ESI-MS/MS. Three of these peptides correspond to fragments of the α-chain of bovine hemoglobin: α107–141, α137–141, and α133–141, and one peptide to the β-chain: β126–145. The minimum inhibitory concentrations (MIC) of these peptides towards the four strains and their hemolytic activity towards bovine erythrocytes were determined.
