Identification
Common NameShiga toxin subunit B
ClassProtein
DescriptionShiga toxin, also called verotoxin, is produced by Shigella dysenteriae. Shiga toxins belongs to the family of A-B5 toxins. The A subunit (32,000 molecular weight) is responsible for the toxic action of the protein, and the B subunit (7,700 molecular weight) is responsible for binding to a specific cell type. (1)

Mechanism of ToxicityShiga toxin causes the glycosidase cleavage of ribosomal eucaryotic 28S rRNA, resulting in inhibition of protein synthesis in susceptible cells. (1)
MetabolismFree toxin may be removed by opsonization via the reticuloendothelial system (primarily the liver and kidneys) or it may be degraded through cellular internalization via the lysosomes. Lysosomes are membrane-enclosed organelles that contain an array of digestive enzymes, including several proteases.
Toxicity ValuesNot Available
Lethal Dose1 nanogram/kg for an adult human. (1)
Carcinogenicity (IARC Classification)No indication of carcinogenicity to humans (not listed by IARC).
Uses/SourcesShiga toxin, also called verotoxin, is produced by Shigella dysenteriae. (1)
