The mechanism of action of trichosanthin on eukaryotic ribosomes--RNA N-glycosidase activity of the cytotoxin.

Trichosanthin is a ribosome-inactivating protein from root tubers of Trichosanthes kirilowii Maxim. In this paper, the mechanism of action of trichosanthin on eukaryotic ribosomes was studied. A fragment of about 450 nucleotides was released from 28S ribosomal RNA after treatment of rat liver riboso... View More
