PKM2 plays key roles in reprogramming cancer cells from energy production to growth (Warburg Effect). The dimeric form of the enzyme is not only less active in glycolysis but can also move into the nucleus to promote the transcription of other cancer-causing genes. A substrate analogon (red) is bound to the active site. PKM2 is a target for anti-cancer therapies. PDB entry: 6WP3.

Medical Laboratory Research Background
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 ball and stick model of a Polytetrafluoroethylene molecule, also known as PTFE or most commonly Teflon. It is a polymer consisting of only carbon and fluorine atoms. It is used as a non-stick coating for cookware, as a lubricant, and it is also used to contain highly reactive chemicals as it is extremely non-reactive.
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.
