生化/生理作用
Ricin A chain inactivates the 60 S ribosomal subunit of eukaryotic cells, inhibiting protein synthesis. This toxic activity is independent of the presence of the B chain of ricin.
其他说明
Ricinus communis toxin (also named RCA60, RCAII, Ricin D, or RCL III) is a highly toxic protein, mol. wt. ~60 kDa, composed of two chains, A and B, connected by a single disulfide bridge.
质量
Electrophoretically pure (SDS-PAGE)
外形
Solution in 40% glycerol containing 10 mM phosphate, pH 6.0, 0.15 M NaCl, 10 mM galactose and 0.5 mM dithioerythritol
制备说明
Purified by affinity chromatography.
分析说明
Agglutination activity is expressed in μg/ml and is determined from serial dilutions in phosphate buffered saline, pH 7.2, of a 1 mg/ml solution. This activity is the lowest concentration to agglutinate a 2% suspension of human erythrocytes after 1 hour incubation at 25°C.

Protein toxins present considerable health risks, but detection often requires laborious analysis. Here, we developed electrochemical aptamer biosensors for ricin and botulinum neurotoxins, which display robust and specific signal at nanomolar concentrations and function in dilute serum. These biosensors may

Incorporation of the rare amino acid selenocysteine to form diselenide bonds can improve stability and function of synthetic peptide therapeutics. However, application of this approach to recombinant proteins has been hampered by heterogeneous incorporation, low selenoprotein yields, and poor fitness

Ricin is a highly toxic ribosome-inactivating lectin occurring in the seeds of castor bean (Ricinus communis L.). Castor bean grows throughout tropical and sub-tropical regions and is a very important crop due to its high seed content of ricinoleic acid
