Snake venomics of the pit vipers Porthidium nasutum, Porthidium ophryomegas, and Cerrophidion godmani from Costa Rica: Toxicological and taxonomical insights
(2012-02-16)
Within the Neotropical pit vipers, a lineage of primarily Middle American snake species
referred to as the “Porthidium group” includes the genera Atropoides, Cerrophidion, and
Porthidium. In this study, the venom proteomes ...
Proteomic and toxicological profiling of the venom of Bothrocophias campbelli, a pitviper species from Ecuador and Colombia
(Toxicon 90, 2014)
Detailed snake venom proteomes for nearly a hundred species in different pitviper genera have accumulated using ‘venomics’ methodologies. However, venom composition for some lineages remains poorly known. Bothrocophias ...
Two phospholipase A2 inhibitors from the plasma of Cerrophidion (Bothrops) godmani which selectively inhibit two different group-II phospholipase A2 myotoxins from its own venom: isolation, molecular cloning and biological properties
(2000-03-15)
Myotoxic phospholipases A2 (PLA2s; group II) account for most of the muscle-tissue damage that results from envenomation by viperid snakes. In the venom of the Godman's viper (Cerrophidion godmani, formerly Bothrops godmani), ...
Tissue Damage and Inflammation Induced by Snake Venoms
(2014-03-27)
Some characteristics of the local tissue damage and inflammatory reactions
induced by snake venoms were analyzed in a mouse model. Tissue damage was
studied by intravital, light, and electron microscopic techniques, and ...
Electrophoretic and immunochemical studies of Micrurus venoms
(1994)
The electrophoretic mobilities of venom components from 15 Micrurus species were studied by polyacrylamide gel electrophoresis. The venoms showed species-specific protein patterns under native (PAGE) or denaturing (urea-PAGE) ...
Snake venomics of monocled cobra (Naja kaouthia) and investigation of human IgG response against venom toxins
(2015-06)
The venom proteome of the monocled cobra, Naja kaouthia, from Thailand, was characterized by RPHPLC,
SDS-PAGE, and MALDI-TOF-TOF analyses, yielding 38 different proteins that were either identified
or assigned to families. ...
Proteomic and functional profiling of the venom of Bothrops ayerbei from Cauca, Colombia, reveals striking interspecific variation with Bothrops asper venom
(Journal of Proteomics Volume 96, 16 January 2014, Pages 159–172, 2014-01)
Bothrops ayerbei, a pitviper inhabiting the Patía River's basin (Valle Alto del Río Patía) in the Southwestern Department of Cauca, Colombia, was considered as a variant form of Bothrops asper prior to being proposed as a ...
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 ...
Venomic and antivenomic analyses of the Central American coral snake, Micrurus nigrocinctus (Elapidae)
(2011-01-31)
The proteome of the venom of Micrurus nigrocinctus (Central American coral snake) was analyzed by a “venomics” approach. Nearly 50 venom peaks were resolved by RP-HPLC, revealing a complex protein composition. Comparative ...
Bactericidal activity of Lys49 and Asp49 myotoxic phospholipases A2 from Bothrops asper snake venom: synthetic Lys49 myotoxin II-(115-129)-peptide identifies its bactericidal region
(1998)
Mammalian group-II phospholipases A2 (PLA2) of inflammatory fluids display bactericidal properties,
which are dependent on their enzymatic activity. This study shows that myotoxins II (Lys49) and III
(Asp49), two group-II ...
