3D cartoon and Gaussian surface models, chain entity color scheme, PDB 4oo8, white background
Aromatase (estrogen synthase) enzyme. Protein responsible for the key step in the synthesis of estrogens. 3D illustration. Cartoon representation.
A ball and stick + ribbons model of human Interleukin 2 or IL-2. Interleukin is a hormone which acts as a signalling molecule for the immune system.
The crystal structure of the tumor marker protein. The 3D model of the biological macromolecule.
Molecular Model of Infliximab, or Remicade, a monoclonal antibody against tumour necrosis factor alpha (TNF-α), which is used to treat autoimmune diseases
Recombinant human insulin. 3d cartoon model based on protein data bank
Transfer RNA (abbreviated tRNA and formerly referred to as sRNA, for soluble RNA with RNA strand in the cell 3d rendering
The ribonucleotide analogue remdesivir (red) inhibits the coronavirus replication by blocking the RNA synthesis in the viral RNA dependent RNA polymerase (RdRp, blue). Four remdesivir molecules have already been attached to the growing RNA chain. Another remdesivir molecule is entering the active site of the RdRp. Source: PDB entry 7l1f.
3D cartoon and Gaussian surface models, PDB 6vg8, white background
Glucose-6-phosphate dehydrogenase (G6PD) protein. Enzyme of the pentose phosphate pathway that generates co-enzyme NADPH. 3D illustration.
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.
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.
Molecular Model of Human Insulin with disulfide bonds shown.
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.
Isolated Proteasome with protein conjugated with ubiquitin 3d rendering
The human immunodeficiency virus single-stranded RNA genome is converted into double-stranded DNA by the viral reverse transcriptase and then the DNA is integrated in the DNA of an infected human cell. The reverse transcriptase is one of the main targets to disrupt the virus multiplication through an inhibitor. There are nucleoside and nucleotide inhibitors and non nucleoside analogue inhibitors.
3D cartoon and Gaussian surface models, chain id color scheme, PDB 5y0m, white background
Bovine beta-lactoglobulin protein, 3D structure. Major whey protein, present in cow milk. Important food allergen.
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.
Calcium-binding atopy-related autoantigen 1, a protein that in humans is encoded by the CBARA1 gene. A calcium binding atopy-related autoantigen. 3d rendering.
Molecular Model of Human Insulin with disulfide bonds shown.
DNA polymerase I. An enzyme that participates in the DNA replication. Shown with a fragment of the DNA
A model of Glutamic Acid, an amino acid. It has an important function in cell metabolism and neurotransmission.
NEK7 plays an important role in mitotic cell cycle progression. It is also involved in the activation of the NLRP3 inflammasome. Source: PDB entries 2WQM, 6NPY
3D cartoon and Gaussian surface models, PDB 3hg3, white background
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.
Rho guanine nucleotide exchange factor 7, which plays a fundamental role in numerous cellular processes that are initiated by extracellular stimuli that work through G protein-coupled receptors.
Molecular Model of DNA.
