The three-dimensional structure of proteins is represented in a variety of conformations. This image is based on the ribbon structure of a protein. It is suitable for biology notebooks and book covers.\nThis image has not been created by AI.
The crystal structure of the tumor marker protein. The 3D model of the biological macromolecule.
3D cartoon and Gaussian surface models, PDB 6vg8, white background
A ball and stick + ribbons model of beta-secretase - a protein that is important in forming healthy peripheral nerve cells, but is also involved in the onset of Alzheimer's disease.
Beta-amyloid (Abeta) peptide, 3D rendering. Major component of plaques found in Alzheimer's disease. Cartoon representation.
Molecular Model of Infliximab, or Remicade, a monoclonal antibody against tumour necrosis factor alpha (TNF-α), which is used to treat autoimmune diseases
Avibactam is a diazobicyclooctane inhibitor of gram-negative and gram-positive bacteria. Avibactam (red) inhibits the bacterial enzyme beta-lactamase (blue) of Clostridioides difficile.
Recombinant human insulin. 3d cartoon model based on protein data bank
Phospholipid bilayer membrane structures that make up living cells and their contents. This is an image of membrane proteins in the membrane.\nThis image, which looks like a plastic model, evokes biology and biochemistry. It can be used as a cover for magazines, textbooks and presentation materials.\nThis image was not created by AI.
Isolated Proteasome with protein conjugated with ubiquitin 3d rendering
3D cartoon and Gaussian surface models. PDB 2aai, white background.
A ball and stick + ribbons model of HIV protease - an enzyme that is the target of much AIDS and HIV research.
Aromatase (estrogen synthase) enzyme. Protein responsible for the key step in the synthesis of estrogens. 3D illustration. Cartoon representation.
DNA A-T Pair
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.
Brain-derived neurotrophic factor (3d), also known as BDNF, a protein that supports the survival of existing neurons, and encourages the growth and differentiation of new neurons and synapses.
The structure of the protein molecule, tumor marker glioblastoma. X-ray crystalline model of the protein encoded by the MELK gene. 3D rendering.
The translation of a nucleotide (DNA or RNA) sequence to a protein sequence 3d rendering
3D cartoon and Gaussian surface models, PDB 1j7n, chain id color scheme, white background
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.
Glucose-6-phosphate dehydrogenase (G6PD) protein. Enzyme of the pentose phosphate pathway that generates co-enzyme NADPH. 3D illustration.
Model of human Insulin, a hormone to regulate carbohydrate and fat metabolism
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.
C-fos-induced growth factor, a vascular endothelial growth factor. The protein encoded by this gene is a member of the PDGF/VEGF family. 3d rendering.
3D CG rendered image of scientifically accurate Avian Infectious Bursal Disease Virus (IBDV) Capsid Structure based on PDB : 1WCD (capsomere)
3D rendering. The structure of the protein molecule, an activator of angiogenesis. X-ray crystalline model of one of the subunits of the hif1A molecule.
3D cartoon model, PDB 5k97, 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.
Indoleamine 2,3 dioxygenase 1 (IDO1) protein. Tryptophan catabolic enzyme of the kynurenine pathway. 3D illustration.
Fibroin is an insoluble protein present in silk created by spiders. 3d illustration
