Bactenecin TFA (Bactenecin, bovine TFA) is a potent 12-aa looped antimicrobial peptide isolated from bovine neutrophils. Bactenecin TFA inhibits the growth of bacteria and yeast, and kills the fungus Trichophyton rubrum. Bactenecin TFA increass membrane permeability, inhibits the growth and biofilm formation of B. pseudomallei[1][2][3].
Bactenecin is synthesized by solid-phase peptide synthesis and renatured to a fully disulfide bonded form. Bactenecin inhibits the growth of Escherichia coli and Staphylococcus aureus at the same concentration reported for the peptide purified from bovine neutrophils. Bactenecin inhibits the growth of other medically important bacteria and yeast, and it kills the fungus Trichophyton rubrum[1]. Bactenecin, a dodecapeptide, is strongly cytotoxic to rat embryonic neurons, fetal rat astrocytes and human glioblastoma cells[2].Bactenecin exhibits stronger binding to LPS and induces perturbation of the inner membrane of live cells. Interaction of Bactenecin with model membranes results in changes in membrane fluidity and permeability, leading to leakage of dye across the membrane[3].
