Preliminary crystallographic data for a new crystalline form of abrin.
نویسندگان
چکیده
A new crystalline form of abrin has been obtained from the most toxic constituent of the seed extract of Abrus precatorius. An x-ray diffraction study shows that the toxin crystallizes in a monoclinic unit cell of probable symmetry P21 and parameters (I = 113 A, b = 72 A, c = 71 A, and /3 = 103”. The asymmetric unit contains 2 protein molecules of molecular weight 63,800 and has a solvent content of approximately 45 % by volume.

Effect of crystalline abrin on the biosynthesis of protein, RNA, and DNA in experimental tumors.
Crystalline abrin isolated from Abrus precatorius L. has been shown to have a strong inhibitory effect on the protein biosynthesis of Ehrlich ascites tumor and Yoshida ascites hepatoma cells and a moderate inhibitory effect on the DNA biosynthesis of these neoplastic cells. It has no significant effects on the RNA biosynthesis and cellular respiration of these neoplastic cells at a much higher ...

Mn doped ZnO nanocrystals were prepared by co-precipitation route sintered at 450 °C temperature. XRD results indicate that the samples having hexagonal (wurtzite) structure. From X-ray data it is found that the lattice parameters increase with increasing Mn concentration. The X-ray density decreases with increasing Mn concentration of Zn 1-x Mnx O nanocrystals. It indicates that the Mn...
متن کاملDetection of Abrin Holotoxin Using Novel Monoclonal Antibodies
Abrin, a member of the ribosome-inactivating protein family, is produced by the Abrus precatorius plant. Having the potential to pose a severe threat to both human and animal health, abrin is classified as a Select Agent by the U.S. Department of Health and Human Services. However, an immunoassay that is specific for intact abrin holotoxin has not yet been reported. In this study, seven new mon...

Introduction: In 1998, the Persian form of Language Assessment, Remediation, & Screening Procedure (P-LARSP) was introduced. However, this adapted version remained on library shelves and was not used by Iranian speech and language pathologists (SLPs). The present study aimed to explore the barriers to using P-LARSP, resolve the possible issues, and provide a preliminary grammatical sketch from ...
متن کاملA Monoclonal–Monoclonal Antibody Based Capture ELISA for Abrin
Abrin, one of the most highly potent toxins in the world, is derived from the plant, Abrus precatorius. Because of its high toxicity, it poses potential bioterror risks. Therefore, a need exists for new reagents and technologies that would be able to rapidly detect abrin contamination as well as lead to new therapeutics. We report here a group of abrin-specific monoclonal antibodies (mAbs) that...
