  • Title: [Ribosome-inactivating lectins from plants].
    Author: Kozlov IuV, Sudarkina OIu, Kurmanova AG.
    Journal: Mol Biol (Mosk); 2006; 40(4):711-23. PubMed ID: 16913230.
    Abstract:
    There is a heterogeneous group of plant proteins which are able to enzymatically inactivate ribosomes by depurination of an invariant adenine from the 28 S ribosomal RNA. Some of these proteins are heterodimers having a lectin subunit which is joined by disulfide bond to the enzymatic subunit. Ricin and abrin which are among the most toxic substances known belong to the last group. This review focuses on the structure of the heterodimeric plant ribosome-inactivating proteins, the way of their action on ribosome, biosynthesis, intracellular trafficking, and their possible usage in medicine.
