Effect of Abrin on Peptide Chain Initiation [PDF]
European Journal of Biochemistry, 1977 Cell‐free systems from wheat germ were preincubated before and after addition of immunoglobulin mRNA to generate systems dependent and independent on peptide chain initiation, respectively. When abrin A chain was added, the system dependent on peptide chain initiation was much more strongly inhibited than the system measuring primarily chain elongation.

Annals of Applied Biology, Volume 184, Issue 1, Page 19-36, January 2024.The dried bean beetle, Acanthoscelides obtectus, is an economically important pest of stored legumes worldwide. We review the semiochemistry of the mate‐ and host‐finding behaviour of A. obtectus and provide new information about the effect of seed chemistry on the sensory and behavioural ecology of host acceptance and larval development.

Advancement of abrin toxin bioforensics capabilities
, 2021 Abrin toxin, located in the seeds of Abrus precatorius, is a potent Type II Ribosome-Inactivating Protein (RIP) A-B subunit toxin that has acquired a heightened biothreat profile over the past decade. Significant research efforts must be made in order to

Detection of Abrin by Electrochemiluminescence Biosensor Based on Screen Printed Electrode
Sensors, 2018 For the convenience of fast measurement in the outdoor environment, a portable electrochemiluminescence biosensor with the screen-printed electrode as the reaction center was developed, which possesses the characteristics of high sensitivity, small scale,

Quantification of Ricinine and Abrine in Human Plasma by HPLC–MS-MS: Biomarkers of Exposure to Ricin and Abrin [PDF]
Journal of Analytical Toxicology, 2018 Ricin and abrin are toxic ribosome-inactivating proteins found in plants. Exposure to these toxins can be detected using the biomarkers ricinine and abrine, which are present in the same plant sources as the toxins. The concentration of the biomarkers in urine and blood will be dependent upon the purification of abrin or ricin, the route of exposure ...

One step Purification and Characterisation of Abrin Toxin from Abrus Precatorius Seeds [PDF]
, 2019 Abrin is a plant toxin obtained from Abrus precatorius seeds. It belongs to the type II ribosomal inactivating proteins (RIPs) consisting of two chains namely, catalytically active A chain and sugar binding B chain linked by a single disulphide bond ...

Influence of Food Matrices on the Stability and Bioavailability of Abrin
Toxins, 2018 Abrin, a highly toxic plant toxin, is a potential bioterror weapon. Work from our laboratory and others have shown that abrin is highly resistant to both thermal and pH inactivation methods.

Chemical Modification of Tryptophan Residues in Abrin-a.
Agricultural and Biological Chemistry, 1991 Chemical modification of tryptophan residues in abrin-a with N-bromosuccinimide (NBS) was studied with regard to saccharide-binding. The number of tryptophan residues available for NBS oxidation increased with lowering pH, and 11 out of the 13 tryptophan residues in abrin-a were eventually modified with NBS at pH 4.0, while 6 tryptophan residues were ...
