Description:Caption:
This represents the seventh slide in a series highlighting the history, chemistry, and uses of ricin, a highly toxic poison made from castor beans. The slide, entitled, “Ricin Molecule”, describes the molecule as a 66kDa heterodimer, bonded by a disulfide bridge, the B-chain (34kDa) binds to cell surface receptors, while the toxin-receptor complex is taken into the cell, the A-chain ((32kDa) has endonuclease activity, and inhibits DNA replication and protein synthesis at low levels (cytotoxin).
