Biophysical Studies of TOAC Analogs of the Ctx(Ile21)-Ha Antimicrobial Peptide Using Liposomes
(2022-06-01)
Antimicrobial peptides (AMP) are innate components of the defense system of many forms of life, composing the first line of defense from invading pathogens. Among many AMPs described in several databases, the Ctx(Ile21)-Ha ...
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 ...
Jelleines: a family of antimicrobial peptides from the Royal Jelly of honeybees (Apis mellifera)
(Elsevier B.V., 2004-06-01)
Four antimicrobial peptides were purified from Royal Jelly of honeybees, by using reverse phase-HPLC and sequenced by using Q-Tof-MS/MS: PFKLSLHL-NH2 (Jelleine-I), TPFKLSLHL-NH2 (Jelleine-II), EPFKLSLHL-NH2 (Jelleine-III), ...
Study of the mechanism of action of anoplin, a helical antimicrobial decapeptide with ion channel-like activity, and the role of the amidated C-terminus
(John Wiley & Sons Ltd, 2008-06-01)
Anoplin, an antimicrobial, helical decapeptide from wasp venom, looses its biological activities by mere deamidation of its C-terminus. Secondary structure determination, by circular dichroism spectroscopy in amphipathic ...
The effect of acidic residues and amphipathicity on the lytic activities of mastoparan peptides studied by fluorescence and CD spectroscopy
(Springer, 2011-01-01)
Some mastoparan peptides extracted from social wasps display antimicrobial activity and some are hemolytic and cytotoxic. Although the cell specificity of these peptides is complex and poorly understood, it is believed ...
Purification and characterization of an antimicrobial peptide produced by Pseudomonas sp strain 4B
(SPRINGER, 2009)
An antimicrobial peptide produced by a bacterium isolated from the effluent pond of a bovine abattoir was purified and characterized. The strain was characterized by biochemical profiling and 16S rDNA sequencing as Pseudomonas ...
Effects of Dimerization on the Structure and Biological Activity of Antimicrobial Peptide Ctx-Ha
(Amer Soc Microbiology, 2012-06-01)
It is well known that cationic antimicrobial peptides (cAMPs) are potential microbicidal agents for the increasing problem of antimicrobial resistance. However, the physicochemical properties of each peptide need to be ...
Contribution of the tyr-1 in plantaricin149a to disrupt phospholipid model membranes
(MDPI AGBasel, 2013-06)
Plantaricin149a (Pln149a) is a cationic antimicrobial peptide, which was suggested to cause membrane destabilization via the carpet mechanism. The mode of action proposed to this antimicrobial peptide describes the induction ...
Gill tissues of the mussel Mytilus edulis chilensis: A new source for antimicrobial peptides
(Pontificia Universidad Católica de Valparaíso, 2005)
Structural and biological characterization of two novel peptides from the venom of the neotropical social wasp Agelaia pallipes pallipes
(Elsevier B.V., 2004-07-01)
The venom of the neotropical social wasp Agelaia pallipes pallipes was fractionated by RP-HPLC resulting in the elution of seven fractions; the last two were re-fractionated under RP-HPLC by using isocratic elution conditions ...
