An acidic phospholipase A2 with antibacterial activity from Porthidium nasutum snake venom
(2012-04)
Snake venoms are complex mixtures of proteins among which both basic and acidic phospholipases A2
(PLA2s) can be found. Basic PLA2s are usually responsible for major toxic effects induced by snake venoms,
while acidic ...
Proteomic analysis of the mandibular glands from the Chinese crocodile lizard, Shinisaurus crocodilurus – another venomous lizard?
(2023)
Based on its phylogenetic relationship to monitor lizards (Varanidae), Gila monsters (Heloderma spp.), and the earless monitor Lanthanotus borneesis, the Chinese crocodile lizard, Shinisaurus crocodilurus, has been assigned ...
First look into the venom of Roatan Island´s critically endangered coral snake Micrurus ruatanus: proteomic characterization, toxicity, immunorecognition and neutralization by an antivenom
(2019)
A proteomic and toxicological study of the venom from one specimen of Micrurus ruatanus, a critically endangered
coral snake species endemic to Roatan Island, Honduras, was carried out. Immunorecognition and
neutralization ...
Biological and structural characterization of crotoxin and new isoform of crotoxin B PLA2 (F6a) from Crotalus durissus collilineatus snake venom
(2006)
A new crotoxin B isoform PLA2 (F6a), from Crotalus durissus collilineatus was purified from
by one step reverse phase HPLC chromatography using l-Bondapack C-18 column analytic.
The new crotoxin B isoform PLA2 (F6a), ...
MipLAAO, a new L-amino acid oxidase from the redtail coral snake, Micrurus mipartitus
(2018-06-08)
L-amino acid oxidases (LAAOs) are ubiquitous enzymes in nature. Bioactivities
described for these enzymes include apoptosis induction, edema formation, induction
or inhibition of platelet aggregation, as well as antiviral, ...
Amino acid sequence and biological characterization of BlatPLA2, a non-toxic acidic phospholipase A2 from the venom of the arboreal snake Bothriechis lateralis from Costa Rica
(2013-10)
Bothriechis is considered a monophyletic, basal genus of arboreal Neotropical pitvipers
distributed across Middle America. The four species found in Costa Rica (B. lateralis, B.
schlegeli, B. nigroviridis, B. supraciliaris) ...
Intravascular hemolysis induced by phospholipases A2 from the venom of the Eastern coral snake, Micrurus fulvius: functional profile of hemolytic and non-hemolytic isoforms
(2018-04)
A unique feature of the venom of Micrurus fulvius (Eastern coral snake) is its ability to induce severe intravascular
hemolysis in particular species, such as dogs or mice. This effect was previously shown to be induced ...
Venomics of Leiurus abdullahbayrami, the most lethal scorpion in the Levant region of the Middle East
(2024)
The scorpion Leiurus abdullahbayrami has been associated with severe/lethal envenomings throughout the Levant region of the Middle East, encompassing Turkey, Syria, and Lebanon, and only scarce information is available on ...
Structural basis for phospholipase A2-like toxin inhibition by the synthetic compound Varespladib (LY315920)
(2019)
The World Health Organization recently listed snakebite envenoming as a Neglected Tropical Disease,
proposing strategies to significantly reduce the global burden of this complex pathology by 2030. In
this context, ...
La actividad proteolítica de los venenos de serpientes de Costa Rica sobre la caseína
(Revista de Biologia Tropical 31(1), 37-40, 1983)
Se establecen las condiciones óptimas para la determinación comparativa de la actividad proteolítica de los venenos de serpientes costarricenses sobre la caseína y se describe dicha actividad para 13 venenos diferentes. ...
