Crystal structure and functional characterization of an Asp49 phospholipase A₂ from the bushmaster (Lachesis muta). [PDF]

Acta Crystallogr F Struct Biol Commun
The crystal structure of an Asp49 phospholipase A2 from L. muta is reported, revealing a tetrameric assembly, catalytic conservation and a polarized electrostatic surface potentially linked to membrane targeting.Snake‐venom phospholipases A2 (PLA2s) are small, structurally conserved enzymes that contribute significantly to the pathophysiology of ...

Intraspecific Differences in the Venom of Crotalus durissus cumanensis from Colombia. [PDF]

Toxins (Basel), 2022
Biochemical and biological differences in the venom of Crotalus durissus cumanensis from three ecoregions of Colombia were evaluated. Rattlesnakes were collected from the geographic areas of Magdalena Medio (MM), Caribe (CA) and Orinoquía (OR). All three regionally distributed venoms contain proteases, PLA2s and the basic subunit of crotoxin.
