Molecular interactions of an ornithine-rich pH-responsive self-Assembling peptide with a model lipid membrane: Conformational aspects
(2016-09-01)
Investigating interactions of designed peptide-based biomaterials with lipid membranes is important for applications in nanobiotechnology. Here the interaction of an ornithine-rich pH-responsive peptide called P11-5 with ...
Monitoring the positioning of short polycationic peptides in model lipid bilayers by combining hydrogen/deuterium exchange and electrospray ionization mass spectrometry
(Elsevier B.V., 2008-12-01)
Electrospray ionization mass spectrometry (ESI-MS) was used to analyze the hydrogen/deuterium exchange properties of the mastoparan peptide Apoica-MP during interactions with lipid vesicle membranes. Synthetic peptide was ...

Lipid-packing perturbation of model membranes by pH-responsive antimicrobial peptides
(2017-10-01)
The indiscriminate use of conventional antibiotics is leading to an increase in the number of resistant bacterial strains, motivating the search for new compounds to overcome this challenging problem. Antimicrobial peptides, ...
The interfacial properties of the peptide Polybia-MP1 and its interaction with DPPC are modulated by lateral electrostatic attractions
(Elsevier Science, 2016-02)
Polybia-MP1 (IDWKKLLDAAKQIL-NH2), extracted from the Brazilian wasp Polybia paulista, exhibits a broad-spectrum bactericidal activity without being hemolytic and cytotoxic. In the present study, we analyzed the surface ...

Dengue fusion peptides in interaction with model membranes-A fluorescence study
(2021-04-01)
Dengue fever is a widespread infectious disease caused by Dengue viruses and responsible for millions of cases per year. One of the key steps during the infection is the fusion between the cell membrane and the lipidic ...
Reversing the peptide sequence impacts on molecular surface behaviour
(Elsevier Science, 2016-03)
The protein's primary structure has all the information for specific protein/peptide folding and, in many cases, can define specific amphiphilic regions along molecules that are important for interaction with membranes. ...
Labaditin, a cyclic peptide with rich biotechnological potential: preliminary toxicological studies and structural changes in water and lipid membrane environment
(Springer, 2011-01-01)
Cyclic peptides isolated from the plants of the Euphorbiaceae family have been largely studied due to their rigid conformation, which is considered significant for biologic activity. The peptide Labaditin (L(0)) and its ...
The lipid composition of a cell membrane modulates the interaction of an antiparasitic peptide at the air-water interface
(Elsevier B.V., 2011-07-01)
The antiparasitic property of peptides is believed to be associated with their interactions with the protozoan membrane, which calls for research on the identification of membrane sites capable of peptide binding. In this ...
