Ricin A-chain, artwork C017 / 3654
Ricin A-chain. Computer artwork showing the enzymatically active A-chain from a molecule of the toxic protein ricin. Ricin comprises two entwined amino acid chains; A (seen here) and B (not shown). The A-chain is toxic, inhibiting protein synthesis in cells and causing cell death. It is carried into cells by the non-toxic B-chain, which is able to bind to the cell surface. Ricin is derived from the seeds of the castor oil plant (Ricinus communis), making it easy to be used as a toxin by bioterrorists. Less than a milligram is enough to kill an adult. Inhaling ricin causes coughing, pulmonary oedema and death. If ingested, it causes gastroenteritis, liver and kidney damage and death from circulatory failure. There is no antidote

EDITORS COMMENTS
This print showcases the intricate artwork of the Ricin A-chain, a toxic protein derived from the seeds of the castor oil plant. Created through computer-generated imagery, this illustration provides a detailed visualization of the enzymatically active A-chain molecule. The complex structure consists of two intertwined amino acid chains, with only the A-chain depicted in this artwork. The toxicity of ricin lies within its A-chain, which has the ability to inhibit protein synthesis in cells and ultimately lead to cell death. However, it is important to note that ricin's toxicity is facilitated by its non-toxic B-chain counterpart, responsible for binding to cell surfaces and allowing entry into cells. With less than a milligram capable of killing an adult, ricin poses a significant threat as a potential weapon for bioterrorists. Inhalation can result in coughing, pulmonary edema, and eventual death while ingestion leads to gastroenteritis and severe damage to vital organs such as liver and kidneys. Unfortunately, there is currently no antidote available for ricin poisoning. This deadly compound serves as a reminder of both its biochemical potency and potential dangers associated with bioterrorism. Ramon Andrade's artistic representation not only highlights the structural composition but also emphasizes the lethal nature of this toxin. Through his meticulous attention to detail and scientific accuracy, he brings forth an image that merges artistry with biochemistry seamlessly.
