A ribbons model of Human Growth Hormone, also known as Somatotropin, with a translucent surface model.
Proteasomes are molecular machines for breaking down proteins called proteolysis, only target proteins that have been marked for destruction called ubiquitin to the target protein, 3d rendering
3D cartoon and Gaussian surface models, PDB 6vg8, white background
DNA A-T Pair
Gamma secretase protein complex. Multi-subunit intramembrane protease that plays role in processing of proteins. 3D illustration.
Abstract geometric shape
Cytochrome P450 molecule. CYP 3A4 is the most promiscuous of the human CYP enzymes. Molecular model. 3D rendering. Illustration
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.
A ball and stick model of Human Insulin. Isolated on black.
Conjugal of DNA to primary antibodies with protein G and linker for multiplexed cellular targeting: 3D rendering
3D cartoon and Gaussian surface models. PDB 3kqg, chain id color scheme, white background.
Model of human Insulin, a hormone to regulate carbohydrate and fat metabolism
c-Myc and Max transcription factors bound to DNA. 3D illustration. Atoms shown as spheres with conventional color coding.
Neurotoxin concept Neurotoxin of type A of bacterium Clostridium botulinum which causes food intoxication botulism, molecular model 3d rendering
Ivermectin 3d rendering. Ivermectin is used to treat human diseases caused by roundworms and ectoparasites. PDB: 3RHW
Avibactam is a diazobicyclooctane inhibitor of gram-negative and gram-positive bacteria.  Avibactam (red) inhibits the bacterial enzyme beta-lactamase (blue) of Clostridioides difficile.
A ribbons model of an antibody, also known as immunoglobin. The immune system produces antibodies (using white blood cells) which then identify and attack viruses and bacteria.
protein G−DNA conjugate an antibody to the intended area on the surface of bioassay chips or particles; 3d rendering
3D cartoon and Gaussian surface models, PDB 7s03, white background
New variant of coronavirus, mutation in the virus's spike protein
Glucose-6-phosphate dehydrogenase (G6PD) protein. Enzyme of the pentose phosphate pathway that generates co-enzyme NADPH. 3D illustration.
3d rendered Gastric inhibitory polypeptide (GIP, glucose-dependent insulinotropic peptide) endocrine protein hormone, 3D illustration
3D CG rendered image of scientifically accurate Adeno-Associated Virus (AAV) Capsid Structure based on PDB : 1LP3 (capsomere)
The NEK-7 independent NLRP3 inflammasome in it's hexameric conformation with ADP (red) bound. Inflammasomes are a promising target for the treatment of autoimmune diseases. PDB entry: 7zgu.
A ribbons + ball-and-stick model of a molecule of Human Leptin, a hormone produced by body fat. Normally, the amount of leptin in the body is proportional to the amount of fat. Leptin reduces appetite and the absence of leptin results in increased food intake and obesity.
A 3D rendering of a SpyTag-SpyCatcher complex with antibody molecule in the white background
3D cartoon and Gaussian surface models, PDB 1j7n, chain id color scheme, white background
The structure of the protein molecule, tumor marker glioblastoma. X-ray crystalline model of the protein encoded by the MELK gene. 3D rendering.
Indoleamine 2,3 dioxygenase 1 (IDO1) protein. Tryptophan catabolic enzyme of the kynurenine pathway. 3D illustration.
3d rendered Gastric inhibitory polypeptide (GIP, glucose-dependent insulinotropic peptide) endocrine protein hormone, 3D illustration
