If a credit card company charges 2% per month, how much would a person have to pay in interest for an amount of $1000 pending for a year at the end of the year.
Cholera toxin is an A-B toxin secreted by V. cholerae that causes the host cell to expel large amounts of water and ions. The toxin is made up of five identical B subunits linked to one A subunit.
A-B Toxins. Most exotoxins are A-B or type III toxins. A-B toxins consist of two polypeptides. The A polypeptide is the enzyme and the B polypeptide is a binding component. B binds to the cell, the complete toxin is taken into the cell, the two subunits separate, and the A subunit enzymatically kills the cell. Membrane Disrupting Toxins. Type II toxins, disrupt host cell plasma membranes.
