Mipartoxin-I, a novel three-finger toxin, is the major neurotoxic component in the venom of the redtail coral snake Micrurus mipartitus (Elapidae)
(2012)The major venom component of Micrurus mipartitus, a coral snake distributed from Nicaragua to northern South America, was characterized biochemically and functionally. This protein, named mipartoxin-I, is a novel member ... -
Identification of linear B-cell epitopes on myotoxin-II, a Lys49 phospholipase A2 homologue from Bothrops asper snake venom
(2012)Knowledge on toxin immunogenicity at the molecular level can provide valuable information for the improvement of antivenoms, as well as for understanding toxin structure– function relationships. The aims of this study ... -
Snake venom Lys49 myotoxins: from phospholipases A2 to non-enzymatic membrane disruptors
(2012-09)Snake venoms often contain toxins that cause a rapid necrosis of skeletal muscle fibers, referred to as myotoxins. The most common among them are phospholipases A2 (PLA2s), enzymes that have two independent evolutionary ... -
A Model Proposal for Augmented Reality Game Creation to Incentivize Physical Activity
(2017)Obesity and a sedentary lifestyle are relevant issues in today’s society. Even though different resources can be used to approach this problem, technology provides endless possibilities to fight against this problem. This ... -
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 ... -
