c-Myc and Max transcription factors bound to DNA. 3D illustration. Atoms shown as spheres with conventional color coding.
DNA Helix - 3d rendered image. Genetic research concept. Complex spiral structure illustration. Medical, science, genetic biotechnology, gene cell, chromosome idea. DNA strands on dark background . Science nanotechnology.
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.

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 + ribbons model of HIV protease - an enzyme that is the target of much AIDS and HIV research.
Avibactam is a diazobicyclooctane inhibitor of gram-negative and gram-positive bacteria.  Avibactam (red) inhibits the bacterial enzyme beta-lactamase (blue) of Clostridioides difficile.
