Destabilization of α-helical structure in solution improves bactericidal activity of antimicrobial peptides: Opposing effects on bacterial and viral targets [PDF]

open access: yes, 2016
We have previously examined the mechanism of antimicrobial peptides on the outer membrane of vaccinia virus. Here we show that the formulation of peptides LL37 and magainin-2B amide in polysorbate 20 (Tween-20™) results in greater reductions in virus ...

Wheat antimicrobial peptides

open access: yesRussian Journal of Genetics: Applied Research, 2013
Antimicrobial peptides (AMPs) are low-molecular-weight defense polypeptides, produced in all living organisms either constitutively or upon perception of signals from pathogenic microorganisms. They are important components of the immune system in both animals and plants. AMPs differ in structure and mode of action. Most of them belong to cysteine-rich

Evidence Supporting an Antimicrobial Origin of Targeting Peptides to Endosymbiotic Organelles

open access: yesCells, 2020
Mitochondria and chloroplasts emerged from primary endosymbiosis. Most proteins of the endosymbiont were subsequently expressed in the nucleo-cytosol of the host and organelle-targeted via the acquisition of N-terminal presequences, whose evolutionary ...

A novel antibacterial peptide derived from Crocodylus siamensis haemoglobin hydrolysate induces membrane permeabilization causing iron dysregulation, oxidative stress and bacterial death [PDF]

open access: yes, 2017
Aims A novel antibacterial peptide from Crocodylus siamensis haemoglobin hydrolysate (CHH) was characterized for antimicrobial activity. Methods and Results CHHs were hydrolysed for 2 h (2 h-CHH), 4 h (4h-CHH), 6 h (6 h-CHH) and 8 h (8 h-CHH). The

Antimicrobial peptides and proteins of the horse - insights into a well-armed organism

open access: yesVeterinary Research, 2011
Antimicrobial peptides play a pivotal role as key effectors of the innate immune system in plants and animals and act as endogenous antibiotics. The molecules exhibit an antimicrobial activity against bacteria, viruses, and eukaryotic pathogens with ...

Polylactic Glycolic Acid-Mediated Delivery of Plectasin Derivative NZ2114 in Staphylococcus epidermidis Biofilms

open access: yesAntibiotics
Antimicrobial peptides (AMPs) are antibiotic candidates; however, their instability and protease susceptibility limit clinical applications. In this study, the polylactic acid–glycolic acid (PLGA)–polyvinyl alcohol (PVA) drug delivery system was screened
