Tetanustoxin B fragment（tet-B)

Tetanus often occurs after trauma. If a body wound is infected by anaerobic Clostridium tetani, the bacteria will grow in a hypoxic environment and produce exotoxins, causing acute and fatal neurological diseases. The clinical manifestations of tetanus are shocking, and it has a high morbidity and mortality rate. Therefore, the disease has attracted great attention and has become a concern of the medical community around the world.

Tetanus toxin (TT) has a full length of 1315 amino acids and a relative molecular mass of approximately 150kDa. It can be cleaved by papain into light and heavy chains connected by disulfide bonds. According to the role of toxins in the body, they are divided into three parts: A, B, and C. Among them, A cannot induce anti-toxin immunity, while B and C both have immune activity, can effectively induce the body's immune response, and can avoid allergies caused by other proteins. However, the B fragment still retains its toxic effects.
