Purification, crystallization and preliminary X-ray structural studies of a 7.2 kDa cytotoxin isolated from the venom of Daboia russelli russelli of the Viperidae family.

ABSTRACT: A cytotoxin (MW 7.2 kDa) from Indian Russell's viper (Daboia russelli russelli) venom possessing antiproliferative activity, cardiotoxicity, neurotoxicity and myotoxicity has been purified, characterized and crystallized. The crystals belong to the tetragonal space group P4(1), with unit-cell parameters a = b = 47.94, c = 50.2 A. Larger crystals, which diffracted to 1.5 A, were found to be twinned; diffraction data were therefore collected to 2.93 A resolution using a smaller crystal. Molecular-replacement calculations identified two molecules of the protein in the asymmetric unit, which is in accordance with the calculated VM value.

Factor V activator from Daboia russelli russelli venom destabilizes β-amyloid aggregate, the hallmark of Alzheimer disease.

Project description:Formation of plaque by fibrils of β-amyloid (Aβ) peptide in the brain is the characteristic feature of Alzheimer disease (AD). Inhibition of the process of aggregate formation from Aβ-monomer and destabilization of the aggregate could be useful for prevention and propagation of the disease respectively. Russell's viper venom (RVV) contains protein(s) that destabilize Aβ aggregates as revealed from the thioflavin T assay. The active component was identified as factor V activator (RVV-V). Among the possible mechanisms of destabilization, RVV-V-mediated proteolysis was ruled out from mass spectrometric data and the thioflavin T assay. The alternate hypothesis that small peptides derived from RVV-V destabilize the aggregate is better supported by experimental results. Six small peptides were synthesized using RVV-V as the template, and three unrelated peptides were synthesized to serve as controls. Destabilization of Aβ aggregate by these peptides was studied using spectrofluorometric assays, atomic force microscopy, transmission electron microscopy, and confocal microscopy. Among the peptides, CTNIF and the mixture of the six peptides were most potent in converting the aggregates to the monomeric state and thus, preventing cytotoxicity in SH-SY5Y human neuroblastoma cells. The control peptides failed to show similar effects. Moreover, some of these peptides are stable in blood for 24 h. Therefore, these venom-derived peptides offer an encouraging opportunity to prevent amyloidosis and may provide information to combat AD.

Phylogenetic analysis of serine proteases from Russell's viper (Daboia russelli siamensis) and Agkistrodon piscivorus leucostoma venom.

Project description:Serine proteases are widely found in snake venoms. They have variety of functions including contributions to hemostasis. In this study, five serine proteases were cloned and characterized from two different cDNA libraries: factor V activator (RVV-V), alpha fibrinogenase (RVAF) and beta fibrinogenase (RVBF) from Russell's viper (Daboia russelli siamensis), and plasminogen activator (APL-PA) and protein C activator (APL-C) from Agkistrodon piscivorus leucostoma. The snake venom serine proteases were clustered in phylogenetic tree according to their functions. K(A)/K(S) values suggested that accelerated evolution has occurred in the mature protein coding regions in cDNAs of snake venom serine proteases.

Isolation, purification, crystallization and preliminary X-ray studies of two 30?kDa proteins from silkworm haemolymph.

Project description:Juvenile hormone-binding protein (JHBP) and the low-molecular-mass lipoprotein PBMHP-12 belong to a group of 30?kDa proteins that comprise the major protein component of the haemolymph specific to the fifth-instar larvae stage of the mulberry silkworm Bombyx mori L. Proteins from this group are often essential for the development of the insect. In a project aimed at crystallographic characterization of B. mori JHBP (BmJHBP), it was copurified together with PBMHP-12. Eventually, the two proteins were isolated and crystallized separately. The BmJHBP crystals were orthorhombic (space group C222(1)) and the PBMHP-12 crystals were triclinic. The crystals diffracted X-rays to 2.9?Å (BmJHBP) and 1.3?Å (PBMHP-12) resolution.

Purification of a phospholipase A(2) from Daboia russelii siamensis venom with anticancer effects.

Project description:Venom phospholipases A2 (PLA(2)) are associated with neurotoxic, myotoxic, cardiotoxic, platelet aggregation, and edema activities. A PLA(2) (Drs-PLA(2)) was purified from Daboia russelii siamensis venom by a two-step purification procedure consisting of size-exclusion, followed by anion exchange high performance liquid chromatography (HPLC). The molecular weight of the Drs-PLA(2) was 13,679Da, which was determined by MALDI-TOF mass spectrometry. Its N-terminal amino acid sequence was homologous to basic PLA(2)s of viperid snake venoms. The Drs-PLA(2) had indirect hemolytic and anticoagulant activities, cytotoxic activity with a CC(50) of 65.8nM, and inhibited SK-MEL-28 cell migration with an IC(50) of 25.6nM. In addition, the Drs-PLA(2) inhibited the colonization of B16F10 cells in lungs of BALB/c mice by ?65%.

Cloning, expression, purification, crystallization and preliminary X-ray analysis of the 31 kDa Vibrio cholerae heat-shock protein VcHsp31.

Project description:The Gram-negative bacterium Vibrio cholerae, which is responsible for the diarrhoeal disease cholera in humans, induces the expression of numerous heat-shock genes. VcHsp31 is a 31 kDa putative heat-shock protein that belongs to the DJ-1/PfpI superfamily, functioning as both a chaperone and a protease. VcHsp31 has been cloned, overexpressed and purified by Ni(2+)-NTA affinity chromatography followed by gel filtration. Crystals of VcHsp31 were grown in the presence of PEG 6000 and MPD; they belonged to space group P2(1) and diffracted to 1.9 Å resolution. Assuming the presence of six molecules in the asymmetric unit, the Matthews coefficient was estimated to be 1.97 Å(3) Da(-1), corresponding to a solvent content of 37.4%.

Purification, crystallization and preliminary X-ray diffraction analysis of saxthrombin, a thrombin-like enzyme from Gloydius saxatilis venom.

Project description:The snake-venom thrombin-like enzymes (SVTLEs) are a class of serine proteinases that show fibrinogen-clotting and esterolytic activities. Most TLEs convert fibrinogen to fibrin by releasing either fibrinopeptide A or fibrinopeptide B and cannot activate factor XIII. The enzymes hydrolyze fibrinogen to produce non-cross-linked fibrins, which are susceptible to the lytic action of plasmin. Because of these physiological properties, TLEs have important medical applications in myocardial infarction, ischaemic stroke and thrombotic diseases. Here, a three-step chromatography procedure was used to purify saxthrombin (AAP20638) from Gloydius saxatilis venom to homogeneity. Its molecular weight is about 30 kDa as estimated by SDS-PAGE. A saxthrombin crystal was obtained using the hanging-drop vapour-diffusion method and diffracted to a resolution limit of 1.43 A. The crystal belongs to space group C2, with unit-cell parameters a = 97.23, b = 52.21, c = 50.10 A, beta = 96.72 degrees , and the Matthews coefficient (V(M)) was calculated to be 2.13 A(3) Da(-1) with one molecule in the asymmetric unit.

Purification, crystallization and preliminary X-ray diffraction analysis of an acidic phospholipase A2 with vasoconstrictor activity from Agkistrodon halys pallas venom.

Project description:Phospholipases A2 (PLA2s) are the major component of snake venoms and exert a variety of relevant toxic actions such as neurotoxicity and myotoxicity, amongst others. An acidic PLA2, here named AhV_aPA, was purified from Agkistrodon halys pallas venom by means of a three-step chromatographic procedure. AhV_aPA migrated as a single band on SDS-PAGE gels, with a molecular weight of about 14?kDa. Like other acidic aPLA2s, AhV_aPA has high enzymatic activity. Tension measurements of mouse thoracic aortic rings remarkably indicated that AhV_aPA could induce a further contractile response on the 60?mM K+-induced contraction, with an EC50 of 369?nmol?l(-1). Rod-shaped crystals were obtained by the hanging-drop vapour-diffusion method and diffracted to a resolution limit of 2.30?Å. The crystals belonged to space group P222, with unit-cell parameters a=44.27, b=68.39, c=81.54?Å.

Purification, crystallization and preliminary X-ray diffraction analysis of a class P-III metalloproteinase (BmMP-III) from the venom of Bothrops moojeni.

Project description:Snake-venom metalloproteinases (SVMPs) comprise a family of haemostatically active toxins which can cause haemorrhage, coagulopathy, inhibition of platelet aggregation and inflammatory response. These effects are attributed to the proteolytic action of SVMPs on extracellular matrix components, plasma proteins and cell-surface proteins. SVMPs are classified into four classes (P-I to P-IV) based on their domain structures. In order to understand the multiple roles played by the domains of P-III SVMPs, a P-III SVMP (BmMP-III) from the venom of Bothrops moojeni was purified, characterized and crystallized. The crystals belonged to space group I4(1)22, with unit-cell parameters a = b = 108.16, c = 196.09 Å. Initially, flash-cooled crystals diffracted poorly to a resolution of about 10 Å. However, a significant improvement in the diffraction resolution was observed upon annealing and a complete data set was collected to 3.3 Å resolution. The asymmetric unit contained one molecule and the structure was determined and partially refined to an R factor of 34%. Structural comparisons indicated that the cysteine-rich domain can adopt different conformations in relation to the catalytic domain, which may modulate the enzyme activity.

Purification, crystallization and preliminary X-ray diffraction of human S100A15.

Project description:Human S100A15 is a novel member of the S100 family of EF-hand calcium-binding proteins and was recently identified in psoriasis, where it is significantly upregulated in lesional skin. The protein is implicated as an effector in calcium-mediated signal transduction pathways. Although its biological function is unclear, the association of the 11.2 kDa S100A15 with psoriasis suggests that it contributes to the pathogenesis of the disease and could provide a molecular target for therapy. To provide insight into the function of S100A15, the protein was crystallized to visualize its structure and to further the understanding of how the many similar calcium-binding mediator proteins in the cell distinguish their cognate target molecules. The S100A15 protein has been cloned, expressed and purified to homogeneity and produced two crystal forms. Crystals of form I are triclinic, with unit-cell parameters a = 33.5, b = 44.3, c = 44.8 angstroms, alpha = 71.2, beta = 68.1, gamma = 67.8 degrees and an estimated two molecules in the asymmetric unit, and diffract to 1.7 angstroms resolution. Crystals of form II are monoclinic, with unit-cell parameters a = 82.1, b = 33.6, c = 52.2 angstroms, beta = 128.2 degrees and an estimated one molecule in the asymmetric unit, and diffract to 2.0 angstroms resolution. This structural analysis of the human S100A15 will further aid in the phylogenic comparison between the other members of the S100 protein family, especially the highly homologous paralog S100A7.

Purification, partial characterization, crystallization and preliminary X-ray diffraction of a novel cardiotoxin-like basic protein from Naja naja atra (South Anhui) venom.

Project description:A novel cardiotoxin-like basic protein was isolated from the venom of the Chinese cobra (Naja naja atra) from the south of Anhui in China. The protein inhibits the expression of vascular endothelial growth factor and basic fibroblast growth factor in human lung cancer cell line H1299 and induces the haemolysis of rabbit erythrocytes under low-lecithin conditions. After a two-step chromatographic purification, the resultant 7 kDa protein was crystallized by the hanging-drop vapour-diffusion method at room temperature. A complete data set was collected to 2.35 A resolution using an in-house X-ray diffraction system. The crystal belongs to space group P4(1)2(1)2, with unit-cell parameters a = b = 43.2, c = 147.9 A. There are two molecules in the crystallographic asymmetric unit.
