Molecular Characterization of Lys49 and Asp49 Phospholipases A2 from Snake Venom and Their Antiviral Activities against Dengue virus
We report the detailed molecular characterization of two PLA₂s, Lys49 and Asp49 isolated from Bothrops leucurus venom, and examined their effects against Dengue virus (DENV). The Bl-PLA₂s, named BlK-PLA₂ and BlD-PLA₂, are composed of 121 and 122 amino acids determined by automated sequencing of the native proteins and peptides produced by digestion with trypsin. They contain fourteen cysteines ...
متن کاملSerum phospholipases A2 in inflammatory diseases.
Phospholipase A2 (EC 3.1.1.4; PLA2) is detected in serum by determination of either the catalytic activity of the enzyme or the concentration of the enzyme protein by immunoassays. The most sensitive methods for determining PLA2 catalytic activity are radiometric assays, with a substrate of synthetic phospholipid (e.g., phosphatidylcholine or phosphatidylethanolamine) containing a 14C- or 3H-la...
متن کاملSerum phospholipases A2 after aortobifemoral reconstruction.
Phospholipase A2 has been implicated in the pathogenesis of local and distant tissue injury after ischaemia and reperfusion. A common operation inducing ischaemia and reperfusion is aortobifemoral reconstruction, during which the aorta is clamped and the blood supply via the inferior mesenteric artery and iliac arteries is interrupted. The purpose of the present work was to study the catalytic ...
متن کاملTemperature Tunability of Dielectric/ Liquid Crystal / Dielectric Photonic Crystal Structures
Recently, photonic crystals doped with liquid crystal (LC) material havegained much research interest. In this article new ternary one-dimensional photoniccrystal introduced and studied. The liquid crystal layer of 5CB and 5PCH is sandwichedby two dielectric layers. For the first time, we use four structures SiO2/UCF35/CaF2,SiO2/5CB/CaF2, NFK51/UCF35/NPSK53 and NFK51/5CB/NPSK53. The effect ofte...
متن کاملLysosomal phospholipases A1 and A2 of bovine adrenal medulla.
1. [(32)P]Lecithin and [(32)P]phosphatidylethanolamine were prepared by incubating rat liver mince with [(32)P]phosphate. With these (32)P-labelled phospholipids conditions for the quantitative assay of phospholipase A activity were established. 2. The distribution of phospholipase A activity between subcellular fractions of the bovine adrenal medulla was determined. Phospholipases A(1) and A(2...
