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.
Abstract geometric shape
Glucose-6-phosphate dehydrogenase (G6PD) protein. Enzyme of the pentose phosphate pathway that generates co-enzyme NADPH. 3D illustration.

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.

3D cartoon and Gaussian surface models, chain id color scheme, PDB 5y0m, white background
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.
Remdesivir is a broad-spectrum antiviral medication, it is a specific treatment for COVID-19. 3d illustration
Multi-colored connected spheres building a molecular structure.
Taq polymerase (Thermus aquaticus polymerase) enzyme bound to DNA, 3D rendering. Protein used in PCR (polymerase chain reaction).

3D cartoon and Gaussian surface models, chain id color scheme, PDB 4ci9, white background
A space-filling molecular model of collagen, a fibrous protein that provides structural support in animals. It has a distinctive triple helix structure. Isolated on black.
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.
