Protonectin (1-6): A novel chemotactic peptide from the venom of the social wasp Agelaia pallipes pallipes
(Toxicon, 2010-11-01) [Artigo]
Peptides constitute the largest group of Hymenoptera venom toxins; some of them interact with GPCR, being involved with the activation of different types of leukocytes, smooth muscle contraction and neurotoxicity. Most of ...
PE and PS lipids synergistically enhance membrane poration by a peptide with anticancer properties
(Biophysical Journal, 2015-09-01) [Artigo]
Polybia-MP1 (MP1) is a bioactive host-defense peptide with known anticancer properties. Its activity is attributed to excess serine (phosphatidylserine (PS)) on the outer leaflet of cancer cells. Recently, higher quantities ...
Formation of a ternary complex for selenocysteine biosynthesis in bacteria
(The Journal Of Biological Chemistry, 2015-09-16) [Artigo]
The synthesis of selenocysteine-containing proteins (selenoproteins) involves the interaction of Selenocysteine Synthase (SelA), tRNA (tRNASec), Selenophosphate Synthetase (SelD, SPS), a specific elongation factor (SelB) ...
Effect of the aspartic acid D2 on the affinity of Polybia-MP1 to anionic lipid vesicles
(European Biophysics Journal With Biophysics Letters, 2014-05-01) [Artigo]
Polybia-MP1 (IDWKKLLDAAKQIL-NH2), a helical peptide extracted from the venom of a Brazilian wasp, has broad-spectrum antimicrobial activities without being hemolytic or cytotoxic. This peptide has also displayed anticancer ...
