DNA A-T Pair
Cholera toxin, molecular model. Cholera toxin (choleragen) is a protein complex secreted by the bacterium Vibrio cholerae, that causes the disease cholera. It is made up of a wedge-shaped A subunit (right part of illustration) and five B subunits (left part of illustration) that form a ring which binds to the intestinal lining. In its most severe forms, cholera is one of the most rapidly fatal illnesses known.
A ball-and-stick molecular model of the hormone Orexin, also known as Hypocretin. Orexin is involved in the regulation of the sleep/wake cycle and it stimulates apetite, wakefulness and energy expenditure. It has been linked with Alzheimer's disease. Isolated on white.
Aztreonam (left, orange) inhibits the beta-lactamase from Acinetobacter species. Avibactam (red) inhibits the beta-lactamase (blue) of Clostridioides difficile.
