Synergistic interaction of PMAP-36 and PRW4 with aminoglycoside antibiotics and their antibacterial mechanism
Abstract The antimicrobial peptide PMAP-36 is a highly cationic and amphipathic α-helical peptide. PRW4 is a truncated analog that replaces paired lysine residues with tryptophan along the N-terminal and deletes the C-terminal hydrophobic tail of PMAP-36. Studies on the two peptides have already bee...

520 | |a Abstract The antimicrobial peptide PMAP-36 is a highly cationic and amphipathic α-helical peptide. PRW4 is a truncated analog that replaces paired lysine residues with tryptophan along the N-terminal and deletes the C-terminal hydrophobic tail of PMAP-36. Studies on the two peptides have already been performed. However, whether there is a synergistic effect with antibiotics has not been investigated, and the study of the antibacterial mechanism of the peptides is inadequate. In this study, antibiotic-peptide combinations were tested against Escherichia coli ATCC 25922 and Staphylococcus aureus ATCC 29213, and the confocal laser scanning microscopy (LSCM) and DNA gel retardation were measured. The results indicated synergy between the peptides and gentamicin when tested against E. coli [fractional lethal concentration (FLC) < 0.5]; partial synergy was observed between the peptides and gentamicin against S. aureus (0.5 < FLC < 1); and streptomycin showed no reaction with the peptides against E. coli and S. aureus (1 < FLC < 4). LSCM and DNA binding suggest that PMAP-36 was able to translocate across the bacterial membranes and interact with intracellular DNA, but PRW4 presented no DNA-binding ability. These results indicate that the combination of PMAP-36 and PRW4 with aminoglycosides may provide useful information for clinical application, and the antibacterial mechanism of peptides likely does not solely involve cytoplasmic-membrane permeabilization. | ||

PRW4 is a truncated analog that replaces paired lysine residues with tryptophan along the N-terminal and deletes the C-terminal hydrophobic tail of PMAP-36. Studies on the two peptides have already been performed. However, whether there is a synergistic effect with antibiotics has not been investigated, and the study of the antibacterial mechanism of the peptides is inadequate. In this study, antibiotic-peptide combinations were tested against Escherichia coli ATCC 25922 and Staphylococcus aureus ATCC 29213, and the confocal laser scanning microscopy (LSCM) and DNA gel retardation were measured. The results indicated synergy between the peptides and gentamicin when tested against E. coli [fractional lethal concentration (FLC) < 0.5]; partial synergy was observed between the peptides and gentamicin against S. aureus (0.5 < FLC < 1); and streptomycin showed no reaction with the peptides against E. coli and S. aureus (1 < FLC < 4). LSCM and DNA binding suggest that PMAP-36 was able to translocate across the bacterial membranes and interact with intracellular DNA, but PRW4 presented no DNA-binding ability. These results indicate that the combination of PMAP-36 and PRW4 with aminoglycosides may provide useful information for clinical application, and the antibacterial mechanism of peptides likely does not solely involve cytoplasmic-membrane permeabilization.

PRW4 is a truncated analog that replaces paired lysine residues with tryptophan along the N-terminal and deletes the C-terminal hydrophobic tail of PMAP-36. Studies on the two peptides have already been performed. However, whether there is a synergistic effect with antibiotics has not been investigated, and the study of the antibacterial mechanism of the peptides is inadequate. In this study, antibiotic-peptide combinations were tested against Escherichia coli ATCC 25922 and Staphylococcus aureus ATCC 29213, and the confocal laser scanning microscopy (LSCM) and DNA gel retardation were measured. The results indicated synergy between the peptides and gentamicin when tested against E. coli [fractional lethal concentration (FLC) < 0.5]; partial synergy was observed between the peptides and gentamicin against S. aureus (0.5 < FLC < 1); and streptomycin showed no reaction with the peptides against E. coli and S. aureus (1 < FLC < 4). LSCM and DNA binding suggest that PMAP-36 was able to translocate across the bacterial membranes and interact with intracellular DNA, but PRW4 presented no DNA-binding ability. These results indicate that the combination of PMAP-36 and PRW4 with aminoglycosides may provide useful information for clinical application, and the antibacterial mechanism of peptides likely does not solely involve cytoplasmic-membrane permeabilization.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">PMAP-36</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">PRW4</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Synergistic interaction</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Aminoglycoside antibiotics</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Antibacterial mechanism</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zhang, Licong</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Wang, Jue</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Wei, Dandan</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Shi, Baoming</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Shan, Anshan</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">World journal of microbiology and biotechnology</subfield><subfield code="d">Dordrecht [u.a.] : Springer Science + Business Media B.V, 1985</subfield><subfield code="g">30(2014), 12 vom: 16.

Synergistic interaction of PMAP-36 and PRW4 with aminoglycoside antibiotics and their antibacterial mechanism |
abstract |
Abstract The antimicrobial peptide PMAP-36 is a highly cationic and amphipathic α-helical peptide. PRW4 is a truncated analog that replaces paired lysine residues with tryptophan along the N-terminal and deletes the C-terminal hydrophobic tail of PMAP-36. Studies on the two peptides have already been performed. However, whether there is a synergistic effect with antibiotics has not been investigated, and the study of the antibacterial mechanism of the peptides is inadequate. In this study, antibiotic-peptide combinations were tested against Escherichia coli ATCC 25922 and Staphylococcus aureus ATCC 29213, and the confocal laser scanning microscopy (LSCM) and DNA gel retardation were measured. The results indicated synergy between the peptides and gentamicin when tested against E. coli [fractional lethal concentration (FLC) < 0.5]; partial synergy was observed between the peptides and gentamicin against S. aureus (0.5 < FLC < 1); and streptomycin showed no reaction with the peptides against E. coli and S. aureus (1 < FLC < 4). LSCM and DNA binding suggest that PMAP-36 was able to translocate across the bacterial membranes and interact with intracellular DNA, but PRW4 presented no DNA-binding ability. These results indicate that the combination of PMAP-36 and PRW4 with aminoglycosides may provide useful information for clinical application, and the antibacterial mechanism of peptides likely does not solely involve cytoplasmic-membrane permeabilization. |
