Venom, venomics, antivenomics
(2009)
Venoms comprise mixtures of peptides and proteins tailored by Natural Selection to act on vital systems
of the prey or victim. Here we review our proteomic protocols for uncoiling the composition,
immunological profile, ...
An overview of Lysine-49 phospholipase A2 myotoxins from crotalid snake venoms and their structural determinants of myotoxic action
(2003)
In 1984, the first venom phospholipase A2 (PLA2) with a lysine substituting for the highly conserved aspartate 49 was
discovered, in the North American crotalid snake Agkistrodon p. piscivorus [J. Biol. Chem. 259 (1984) ...
Structure of myotoxin-II, a catalytically inactive Lys49 phospholipase A2 homologue from Atropoides nummifer venom
(2006)
Lys49 snake-venom phospholipase A2 (PLA2) homologues are highly myotoxic
proteins which, although lacking catalytic activity, possess the ability to disrupt
biological membranes, inducing significant muscle-tissue loss ...
Tyr→Trp-substituted peptide 115-129 of a Lys49 phospholipase A2 expresses enhanced membrane-damaging activities and reproduces its in vivo myotoxic effect
(1999)
Myotoxin II is a group II Lys49 phospholipase A2 (PLA2) isolated from the venom of the snake Bothrops asper. Previous
studies on a synthetic peptide derived from its heparin-binding, cationic/hydrophobic sequence 115^129 ...
Antimicrobial activity of myotoxic phospholipases A2 from crotalid snake venoms and synthetic peptide variants derived from their C-terminal region
(2005)
A short peptide derived from the C-terminal region of Bothrops asper myotoxin II, a Lys49 phospholipase A2 (PLA2), was
previously found to reproduce the bactericidal activity of its parent molecule. In this study, a panel ...
Structural characterization and phylogenetic relationships of myotoxin II from Atropoides (Bothrops) nummifer snake venom, a Lys49 phospholipase A2 homologue
(2002)
In order to analyze its structure–function relationships, the complete amino acid sequence of myotoxin II from Atropoides
(Bothrops) nummifer from Costa Rica was determined. This toxin is a Lys49-type phospholipase A2 ...
Immunochemical properties of the N-terminal helix of myotoxin II, a lysine-49 phospholipase A2 from Bothrops asper snake venom
(2001)
Myotoxic class II phospholipases A2 from snake venoms can be divided into Asp49 and Lys49 types. The latter, including
Bothrops asper myotoxin II, exert membrane damage despite lacking catalytic activity. A heparin-binding, ...
Método para la producción de formulaciones inyectables de productos proteicos hemoderivados y productos obtenidos utilizando dicho método
(2011-04-08)
The invention relates to a method for producing injectable pharmaceutical formulations of blood-derived protein materials, including the steps of fractioning the source material in a polymer/salt aqueous two-phasesystem ...
