Organization of the gene for batroxobin, a thrombin-like snake venom enzyme. Homology with the trypsin/kallikrein gene family.
We have isolated and analyzed the gene for batroxobin, a thrombin-like snake venom enzyme. Three overlapping DNA segments containing the entire batroxobin gene were identified. Sequence analysis revealed that the batroxobin gene spans 8 kilobase pairs and contains five exons. Mature batroxobin is encoded by four separate exons, 2 to 5. The catalytic residues of batroxobin, His-41, Asp-86, and S...
متن کاملMolecular 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 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...
متن کاملthe study of aaag repeat polymorphism in promoter of errg gene and its association with the risk of breast cancer in isfahan region
چکیده: سرطان پستان دومین عامل مرگ مرتبط با سرطان در خانم ها است. از آنجا که سرطان پستان یک تومور وابسته به هورمون است، می تواند توسط وضعیت هورمون های استروئیدی شامل استروژن و پروژسترون تنظیم شود. استروژن نقش مهمی در توسعه و پیشرفت سرطان پستان ایفا می کند و تاثیر خود را روی بیان ژن های هدف از طریق گیرنده های استروژن اعمال می کند. اما گروه دیگری از گیرنده های هسته ای به نام گیرنده های مرتبط به ا...
15 صفحه اولThe 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...
