Molecular cloning and sequence analysis of cDNA for batroxobin, a thrombin-like snake venom enzyme.
Determination of the nucleotide sequence of a cDNA for batroxobin, a thrombin-like enzyme from Bothrops atrox, moojeni venom, allowed elucidation of the complete amino acid sequence of batroxobin for the first time for a thrombin-like snake venom enzyme. The molecular weight of batroxobin is 25,503 (231 amino acids). The amino acid sequence of batroxobin exhibits significant homology with those...
متن کاملMolecular cloning and sequence analysis of the cDNA for ancrod, a thrombin-like enzyme from the venom of Calloselasma rhodostoma.
The 1.54 kb cDNA for ancrod, a thrombin-like enzyme, was cloned from a lambda ZAP cDNA library derived from the venom glands of Calloselasma (Agkistrodon) rhodostoma. The cDNA sequence reveals that ancrod is synthesized as a pre-zymogen of 258 amino acids, including a putative secretory peptide of 18 amino acids and a proposed zymogen peptide of 6 amino-acid residues. The amino-acid sequence of...
متن کاملThe Thrombin-like Enzyme from Bothrops atrox Snake Venom PROPERTIES OF THE ENZYME PURIFIED BY AFFINITY CHROMATOGRAPHY
The thrombin-like activities from the snake venoms of two subspecies of Bothrops atrox, moojeni (type I) and marajoensis (type II), were purified to homogeneity by affinity chromatography on a support consisting of the inhibitor, p-aminobenzamidine, linked to Sepharose 4B with a spacer of diaminodipropylaminosuccinate. At room temperature the enzyme was not bound to the affinity support but rat...
متن کاملIsolation and Biochemical Characterization of a New Thrombin-Like Serine Protease from Bothrops pirajai Snake Venom
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 SDS-PAGE and confirmed by mass spectrometr...
متن کاملPurification and Partial Characterization of a Thrombin-Like Enzyme (AH144) from Venom of Iranian Snake Agkistrodon Halys
The snake venom´s thrombin-like enzymes comprise a number of serine proteases, which are functionally and structurally related to thrombin. Purification and partial characterization of a thrombin-like enzyme from the venom of the Iranian snake, Agkistrodon halys, was the aim of this study. Purification was carried out by a combination of variety of chromatographic methods that included: gel...
