Purification and Biochemical Characterization of Three Myotoxins from Bothrops mattogrossensis Snake Venom with Toxicity against Leishmania and Tumor Cells

open access: yesBioMed Research International, Volume 2014, Issue 1, 2014., 2014
Bothrops mattogrossensis snake is widely distributed throughout eastern South America and is responsible for snakebites in this region. This paper reports the purification and biochemical characterization of three new phospholipases A2 (PLA2s), one of which is presumably an enzymatically active Asp49 and two are very likely enzymatically inactive Lys49

Inhibitory Effect of Plant Manilkara subsericea against Biological Activities of Lachesis muta Snake Venom

open access: yesBioMed Research International, Volume 2014, Issue 1, 2014., 2014
Snake venom is composed of a mixture of substances that caused in victims a variety of pathophysiological effects. Besides antivenom, literature has described plants able to inhibit injuries and lethal activities induced by snake venoms. This work describes the inhibitory potential of ethanol, hexane, ethyl acetate, or dichloromethane extracts and ...

Isolation and Biochemical Characterization of a New Thrombin‐Like Serine Protease from Bothrops pirajai Snake Venom

open access: yesBioMed Research International, Volume 2014, Issue 1, 2014., 2014
This paper presents a novel serine protease (SP) isolated from Bothrops pirajai, a venomous snake found solely in Brazil that belongs to the Viperidae family. The identified SP, named BpirSP‐39, was isolated by three chromatographic steps (size exclusion, bioaffinity, and reverse phase chromatographies). The molecular mass of BpirSP‐39 was estimated by

Alkylation of Histidine Residues of Bothrops jararacussu Venom Proteins and Isolated Phospholipases A2: A Biotechnological Tool to Improve the Production of Antibodies

open access: yesBioMed Research International, Volume 2014, Issue 1, 2014., 2014
Crude venom of Bothrops jararacussu and isolated phospholipases A2 (PLA2) of this toxin (BthTX‐I and BthTX‐II) were chemically modified (alkylation) by p‐bromophenacyl bromide (BPB) in order to study antibody production capacity in function of the structure‐function relationship of these substances (crude venom and PLA2 native and alkylated).
