Expression and functional properties of genetically engineered ricin B chain lacking galactose-binding activity.

Biochimica et biophysica acta - 21 Jun 1990

Vitetta E S, Yen N

Abstract excerpt

Ricin is a potent plant toxin consisting of two disulfide-bonded subunits. The A chain of ricin is an N-glycosidase which inactivates 28 S RNA and inhibits protein synthesis. The B chain is a galactose-specific lectin with two galactose-binding sites. The genes encoding preproricin and its A and B chains have been cloned and expressed. In addition, X-ray crystallographic studies have identified the...
