c-Myc and Max transcription factors bound to DNA. 3D illustration. Atoms shown as spheres with conventional color coding.
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.
Avibactam is a diazobicyclooctane inhibitor of gram-negative and gram-positive bacteria.  Avibactam (red) inhibits the bacterial enzyme beta-lactamase (blue) of Clostridioides difficile.
Rendered coronavirus/2019-nCoV single-stranded RNA, built from experimentally determined Ebola virus crystal structure. Color symbols - bluewhite=carbon, pink=oxygen, lightblue=nitrogen, white=hydrogen, lavender=phosphorus

Glucose-6-phosphate dehydrogenase (G6PD) protein. Enzyme of the pentose phosphate pathway that generates co-enzyme NADPH. 3D illustration.
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.
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.
Rendered Remdesivir molecule in 3D, an experimental drug from Gilead, used to cure the first case of 2019-nCoV in the United States (for a patient at Seattle, Washington). The model showed accurate atom connection and stereochemistry, based on the chemical structure available in public space from U.S. National Library of Medicine, which was professionally checked. Color symbols - green=carbon, red=oxygen, blue=nitrogen, white=hydrogen, purple=phosphorus
Cytochrome P450 molecule. CYP 3A4 is the most promiscuous of the human CYP enzymes. Molecular model. 3D rendering. Illustration
DNA A-T Pair
3D cartoon and Gaussian surface models, chain id color scheme, PDB 5y0m, white background
3d Rendering Abstract Colorful Molecules on Black Background
Botulinum toxin neurotoxic protein, 3D rendering. Produced by Clostridium botulinum. Cosmetically used to treat wrinkles.
A molecular model of Human Insulin. 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.
Isolated Proteasome with protein conjugated with ubiquitin 3d rendering
Afamelanotide is a synthetic peptide stimulating hormone used to prevent skin damage from the sun. 3d illustration
molecular model of Sovaldi (generic name: Sofosbuvir), the most popular drug to treat hepatitis C infection
3D cartoon and Gaussian surface models. PDB 2aai, white background.
3D CG rendered image of scientifically accurate Enterobacteria Bacteriophage phiX174 Capsid Structure based on PDB : 1CD3 (capsomere)
Indoleamine 2,3 dioxygenase 1 (IDO1) protein. Tryptophan catabolic enzyme of the kynurenine pathway. 3D illustration.
A ball and stick + ribbons model of HIV protease - an enzyme that is the target of much AIDS and HIV research.
Main mutation site of the coronavirus variant B.1.531 emerged in South Africa. The spike protein (red) is bound to the angiotensin converting enzyme 2 (blue). The mutation is at the amino acid position 484 (yellow). Source: PDB entry 6cs2.
