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.
Multi-colored connected spheres building a molecular structure.
PETase (left) degrades polyethylene terephtalate (PET) into monohydroxyethyl terephthalate (MHET) and MHETase degrades MHET ethylene glycol (EG) and terephthalic acid (TPA). The substrates in the binding sites are depicted in red.
A model of a molecule of arginine, an amino acid. Amino acids are the building blocks of proteins and have many functions in metabolism. In particular, Arginine has an important function in the immune system, wound healing and cell division.
Botulinum toxin neurotoxic protein, 3D rendering. Produced by Clostridium botulinum. Cosmetically used to treat wrinkles.
