Venom Ontogeny in the Mexican Lance-Headed Rattlesnake (Crotalus polystictus) [PDF]

, 2018
As trophic adaptations, rattlesnake venoms can vary in composition depending on several intrinsic and extrinsic factors. Ontogenetic changes in venom composition have been documented for numerous species, but little is known of the potential age ...

Single-step purification of crotapotin and crotactine from Crotalus durissus terrificus venom using preparative isoelectric focusing

Brazilian Journal of Medical and Biological Research, 1997
We describe the isolation of crotoxin, a presynaptic B-neurotoxin, as well as its subunits B (crotactine) and A (crotapotin) from lyophilized Crotalus durissus terrificus venom by a single-step preparative isoelectric focusing procedure.

Identification, description and structural analysis of beta phospholipase A2 inhibitors (sbβPLIs) from Latin American pit vipers indicate a binding site region for basic snake venom phospholipases A2

Toxicon: X, 2019
Several snake species possess, in their circulating blood, endogenous PLA2 inhibitors (sbPLIs) with the primary function of natural protection against toxic enzymes from homologous and heterologous venoms.

Can Inhibitors of Snake Venom Phospholipases A2 Lead to New Insights into Anti-Inflammatory Therapy in Humans? A Theoretical Study

Toxins, 2017
Human phospholipase A2 (hPLA2) of the IIA group (HGIIA) catalyzes the hydrolysis of membrane phospholipids, producing arachidonic acid and originating potent inflammatory mediators.

Rabbit IgG antibodies against phospholipase A2 from Crotalus durissus terrificus neutralize the lethal activity of the venom [PDF]

, 2006
Crotalus durissus terrificus (C.d.t.) (South American rattlesnake) venom possesses myotoxic and neurotoxic activities, both of which are also expressed by crotoxin, the principal toxin of this venom.

Conformation of the neurotoxin crotoxin complex and its subunits

Biochemistry, 1979
Crotoxin, the neurotoxin from Crotalus durissus terrificus venom, and its two subunits, crotoxin A and crotoxin B, have been examined by fluorescence and circular dichroism techniques. Model spectra of crotoxin, generated from the expected contributions of the individual subunits, agreed with experimental results only at pH 2, where crotoxin was fully ...
