Ricin, ricin agglutinin, and the ricin binding subunit structural comparison by Raman spectroscopy
Journal of Molecular Structure, 2005Raman spectroscopy is used to study conformation-sensitive vibrational bands of the plant toxins ricin and ricin agglutinin and the ricin binding subunit in aqueous solution. The analysis of the Raman data yields the conformational state of the protein molecules differing from that predicted by the X-ray data.

Cell toxicity by ricin and elucidation of mechanism of Ricin inactivation
International Journal of Biological Macromolecules, 2018 Castor cake is a by-product of the extraction of oil from from seeds of castor plants (Ricinus communis). This by-product contains high levels of proteins, but a toxic protein, ricin, limits its use as an animal feed. Ricin can be efficiently inactivated by treatment with calcium oxide (CaO), which can be evaluated by a cytotoxicity assay using LLC-MK2

Membrane destabilization by ricin
European Biophysics Journal, 2004Ricin is a promising candidate for the treatment of cancer because it can be selectively targeted to tumor cells via linkage to monoclonal antibodies. Biochemical evidence suggests that escape of ricin or its ribosome-inactivating subunit from an intracellular compartment is mediated by retrograde transport to the endoplasmic reticulum and subsequent ...

Bacterial and plant toxins composed of different protein subunits with diverse biological functions have provided an investigational focal point for researchers in many areas of specialization. Potent catalytic toxins have been linked to monoclonal antibodies (MoAb) for antibody directed cell targeting.

In this chapter we discuss vaccines to protect against the highly toxic plant-derived toxin, ricin. Due to its prevalence, ease of use, and stability it has been used in sporadic incidents of espionage. There is also concern that it will be used as an agent of bioterrorism.

Abstract Ricin is a highly cytotoxic lectin derived from the seed of the castor bean, Ricinis communis (Euphorbiaceae). Aqueous extracts of the bean contain two different lectins: the cytotoxic RCA11 (ricin) and a hemagglutinin RCA1. The entire plant of the castor bean is toxic: in addition to the lectins, there is a powerful allergen

Experiments on the detoxification of ricin
Toxicology, 1973Abstract Irradiation with ultraviolet light has been shown to affect the ricin molecule in a way which leads to a significantly decreased acute toxicity on i.p. administration to mice.
