Full textA L-Aminoacid oxidase enzyme was purified and characterized from Bothrops atrox snake venom by two steps. It used a Sephadex G-100 column and ion exchange on CM-Sephadex C-50 at pH 6. The purification grade was 12,14 folds with a specific activity of 4,13 U/mg. This enzyme with a molecular weight of 127,879 daltons as determined by gel filtration is a noncovalent dimmer consisting of two subunits with a molecular weight each of 63,128 daltons as determined by SDS-PAGE, with at least one intrachain disulfide bond that is important for its activity. The enzyme exhibited a optimun pH of 8,3 using L- leucine as substrate. It is an acid glicoprotein containing 17% carbohydrate, being thermoestable till 55 ºC, labil to alkaline pH and susceptible to presence of Zn 2+. The antigenicity and homogeneity of enzyme was demonstrated by inmunodiffusion and inmunoelectrophoresis using polivalent antibothropic antivenom. Beside antibacterial effect of whole venom as well as purified enzyme was demonstrated by Grove’s method on Staphylococcus aureus, Streptococcus faecalis, Vibrio cholerae and Escherichia coli grown cultures, being Gram positive bacterials, more susceptible than Gram-negative bacterials. Moreover B. atrox crude venom and its purified enzyme LAO, presented an in vitro effect against Leishmania braziliensis braziliensis promastigotes with an EC50 of 7,82 and 1,33 μg/ml respectively, and Trypanosoma cruzi epimastigotes with an EC50 of 7,95 ug/ml for whole venom and 1,38 μg/ml for purified enzyme. LAO does not have haemorragic nor hemolytic activities on mouse skin (20-22 g body weight) and human red blood cells respectively. However LAO produces edema with a DEM of 15,18 μg of protein. Key words: L-amino acid oxidase, snake, enzyme, Bothrops atrox, venom

Full text--- A thrombin- like enzyme was purified from Bothrops barnetti peruvian snake venom using CM Sephadex C-50 followed by Sephadex G-100, in both two cases with 0,05 M Amonium Acetate buffer pH 5,0. The enzyme was purified 45 fold with 14% of yield and the PAGE-SDS showed only protein band of 52 kDa under reducing condition with 2β-Mercaptoetanol and 48 kDa under non reducing condition indicating that the enzyme has a single polypeptide chain with disulfide bond. The PNGase treatment showed that it is a basic glycoprotein containing 45% total carbohydrates. The enzyme has coagulant activity on fibrinogen and citrated plasma and amidolytic activity on BApNA and Chromozym TH. The coagulant potency was equivalent to 131 NIH thrombin Units/ mg. In addition the enzyme is inhibited by PMSF and soybean trypsin inhibitor suggesting that is a serine proteinase. The enzyme had optimal amidolytic activity pH was 8,0 and is stable until 40 ºC. The antigenicity and neutralization of enzyme was demonstrated by inmunodiffusion and inmunoelectrophoresis with the polyvalent antibothropic serum on citrated plasma (ED: 250 µl of antivenom/ mg of enzyme). Key words: Venom, snake, enzyme, thrombin like, Bothrops barnetti, coagulant.

Full text--- In the present research some biochemical and biological characteristics of a hyaluronidase from the venom of Lachesis muta snake were evaluated. In this way the method for purification of this enzyme was improved. 50 mg of whole venom was disolved in 0.05 M amoniun acetate buffer pH 5.0 and applied to Sephadex G-100 gel filtration chromatography followed by CM Sephadex C-50 exchange chromatography using the same buffer. In the last system, the enzyme was recovered after a gradient of NaCl from 0 to 0,7 M with 51,4 folds and 39,02% of yield. The hyaluronidase was achieved as homogeneus band of protein by PAGE-SDS with 65 kDa of molecular weigth. The enzyme registered 5,0 as optimus pH, Km: 34,4 µg of hyaluronic acid/ml and Vmax: 40.9 µg hidrolizade hyaluronic acid/minute/mg. The enzyme showed a total dependence for Cl- and Br- ions. The biological activity assays using agar-blood plates showed the hyaluronidase was a spreading factor, because of hemolisis by phospholipase A2 ocurred using the total venom. In addition, any biological effect was observed after inoculation of 0,4 to 1,6 mg of the hyaluronidase on mice.

Full textAn L-amino acid oxidase from Bothrops atrox venom was purified and its kinetic properties determinated. Purification procedure was carried out through two chromatography steps: a size exclusion chromatography on Sephadex G-75, followed by an ion exchange chromatography on CM-Sephadex C-50. This enzyme had a molecular weight of 54.6 kDa calculated by SDS-PAGE. Between substrates assayed to pH 8.5, LAO had higher specific activity on L-phenilalanine followed by L-leucine, L-metionine and L-arginine. These were in a range of pH 6.9 to 9.6 being optimum values of 8.1 for L-metionine, 8.9 for L-arginine, and 8.2 for L-fenilalanine. Kinetics parameters (Km, Vmax, Kcat and Kcat/Km) for these L-amino acids were determinated at pH 7.5 and 8.5. According to catalytic efficiency, we found that L-leucine was the best substrate at pH 7.5 (Kcat/km same to 40.903 x 104 s-1 M-1) and 8.5 (Kcat/km same to 71.213 x 104 s-1 M-1). By the way, we evaluated enzyme inhibition at pH 8.5 using anthranilic, benzoic, salicylic and sulphanylic acid, determinating the best model of enzyme inhibition as well as Ki values. The minimal Ki value was for anthranilic acid Ki (0.0082 mM), fitting it to a non-competitive model. Benzoic acid was considered a competitive inhibitor, while salicylic and sulphanylic acid showed mixed-type inhibition.

Full textWe have determinated the main biochemical and immunological properties of a thrombin-like enzyme (TLE) isolated from Bothrops atrox Peruvian snake venom (“jergón”). In this concern, TLE was purified until homogeneity using three chromatographical steps on Sephadex G-75, CM-Sephadex C-50 and Agarose-PAB. Furthermore, molecular weight was determinate by PAGE-SDS and associated carbohydrates by hydrolysis and analysis of hexoses, hexosamines and sialic acid. Then, fibrinocoagulant, amidolytic and sterasic activities were measured on bovine fibrinogen, BApNA and BAEE, respectively, hydrolysis on S-2238, S-2251 and S-2266 chromogenic substrates, and finally molecular identity of this enzyme was determinated by peptide mass fingerprinting technique. For the immunochemical analyses, white rabbits were immunized with 150 µg of EST and a hyperimmune serum anti-TLE was obtained. Patterns of immunological reactivity were determined between this serum against TLE and venoms of Bothrops atrox, Bothrops brazili, Lachesis muta y Crotalus durissus using ELISA technique. As a result of biochemical analysis, we determined that this enzyme represents 1.7% of total venom and was 25.5-fold purified with a 43.3% yield, using BApNA as substrate. This enzyme had 29.6 kDa, where 14.2% was associated carbohydrates. The TLE of B. atrox produced coagulation of bovine fibrinogen and had enzymatic activity on BAEE, BApNA, S-2238 and S-2266, being unable to act on S-2251. Mass spectrometry analysis of hydrolyzed EST of B. atrox results on a 75% sequence homology with venombin A protein. At the final of immunization protocol, we obtained an anti-TLE hyperimmune serum with a title of 64000, which showed the potential immunogenicity of this protein. On the other hand, raised antibodies cross-reacted with total venoms of B. atrox (9.9%) y B. brazili (9.6%) and with less intensity with those from L. muta and C. durissus (5.1% and 4.8%, respectively).

Full textThe Lachesis muta’s envenomations induce a complex physiopathology due to the presence of numerous enzymes group such as Phospholipase A2 (PLA2). For this reason, in the present study have been investigated some biochemistries’ properties of PLA2 and its in vitro and in vivo biologics effect. Initially, the enzyme was purified in two chromatographics steps, CM-Sephadex C-50 followed by Sephadex G-50, obtaining a purification factor of 55.3 times and with a yield of 34.1% and a unique protein band of 18749 Da was obtained by SDS-PAGE analysis under reducing and non-reducing conditions, indicating that PLA2 is a monomeric protein. The protein is thermostable maintaining its total activity until 100ºC per 10 minutes, so, it is a Calcium ion depending protein and the activity was strongly inhibited by glutation, cistein, ESTA and PMSF which reduce until more 50% of PLA2 activity. As far as its biologic activity was obtain that Media Hemolytic Doses (DH50) was 4.35µg and 67.6µg to pure enzyme and crude venom respectively, this indicate that PLA2 is 15,5 times more hemolytic than crude venom. Likewise, had demonstrated that Minimum Miotoxic Doses (MMD) is very low to PLA2 (125. 89 μg/ml) while to crude venom was 144,21 μg/ml. The enzyme’s Minimum Edematic Doses (MED) was 91.5 μg. For another hand, the PLA2 didn´t show any hemorrhagic activity until 30 μg but it showed has anticoagulant activity on citrated plasma when the PLA2 concentration was increasing. Additionally, the inmunodiffusion and inmunoelectrophoresis probes showed PLA2 had inmunogenic reactivity against anti lachesic nonovalent serum (INS-Perú), as well as a partial enzymatic activity and hemolytic neutralization.

Production of specific avian immunoglobulin Y is an alternative in relationship IgG horse antibodies, which is the main point of this research. Laying Light Brow Leghorn chickens were immunizated with 500 µg of Bothrops atrox snake venom emulsificated with Complete Freund’s adjuvant, and the IgY antibodies production was evaluated with the double immunodiffusion method. The avian antibodies were isolated from egg yolk which contained high level of specific IgY, calculated by ELISA method. Using caprylic acid negative precipitation and ammonium sulfate positive precipitation, mass antibodies recovery was 8,5 ± 1,35 mg/ml of yolk and after step on sepharosa 4B-venom affinity chromatographic, specific IgY recovery was 8,3% . The avian antivenom had a ED50: 575 µL antivenom/mg of venom and potency was 1,74 mg of venom/ml of avian antivenom. In addition, the crossing reactivity assays showed that Bothrops brazili venom share more common epitope with Bothrops atrox venom with a value of 46% of crossing reactivity whilest the Bothrops pictus and Bothrops barnetti venoms had values of 41% and 37% respectly; in contrast the venoms of Crotalus durissus (12%) and Lachesis muta (19%) had low crossing reactivity with Bothrops atrox venom.
