Investigating the effect of different positioning of lysine residues along the peptide chain of mastoparans for their secondary structures and biological activities
(Amino Acids, 2011-01-01) [Artigo]
In order to investigate the effect of the different positions of the positive charges generated by the ionization of the side-chain of lysine residues, on the structure-activity relationship of the mastoparans, the peptides ...
Characterization of two novel polyfunctional mastoparan peptides from the venom of the social wasp Polybia paulista
(Peptides, 2009-08-01) [Artigo]
Hymenoptera venoms are complex mixtures of biochemically and pharmacologically active components such as biogenic amines, peptides and proteins. Polycationic peptides generally constitute the largest group of Hymenoptera ...
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 ...
Hyperalgesic and edematogenic effects of Secapin-2, a peptide isolated from Africanized honeybee (Apis mellifera) venom
(Peptides, 2014-09-01) [Artigo]
Honeybee stings are a severe public health problem. Bee venom contains a series of active components, including enzymes, peptides, and biogenic amines. The local reactions observed after envenoming include a typical ...
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) ...
Conformation and lytic activity of eumenine mastoparan: A new antimicrobial peptide from wasp venom
(Journal of Peptide Research, 2004-09-01) [Artigo]
Eumenine mastoparan-AF (EMP-AF) is a novel membrane active tetradecapeptide recently isolated from the venom of solitary wasp, Anterhynchium flavomarginatum micado. It was reported previously that EMP-AF peptide presented ...
