3D cartoon and Gaussian surface models, chain entity color scheme, PDB 4oo8, white background
Beta-amyloid (Abeta) peptide, 3D rendering. Major component of plaques found in Alzheimer's disease. 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.
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.
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
Isolated Proteasome with protein conjugated with ubiquitin 3d rendering
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
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 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 DNA.
Fibroin is an insoluble protein present in silk created by spiders. 3d illustration
The coronavirus 3CL hydrolase enzyme is essential for the maturation of the virus. It can be a promising target for drugs that would inhibit cleavage of the viral polyprotein and prevent spread of the infection. Source: PDB entry 6LU7
3D model of a protein molecule. The spatial oriented structure of the macromolecule.
3D cartoon model, secondary structure color scheme, PDB 2rfn, 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 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.
Alpha-actinin 2, a protein which crosslinks filamentous actin molecules and titin molecules from adjoining sarcomeres at Z-discs, a function that is modulated by phospholipids. 3d rendering.
3D CG rendered image of scientifically accurate Avian Infectious Bursal Disease Virus (IBDV) Capsid Structure based on PDB : 1WCD (capsomere)
DNA polymerase I. An enzyme that participates in the DNA replication. Shown with a fragment of the DNA
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 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 and Gaussian surface models. PDB 3kqg, chain id color scheme, white background.
Indoleamine 2,3 dioxygenase 1 (IDO1) protein. Tryptophan catabolic enzyme of the kynurenine pathway. 3D illustration.
A model of a benzopyrene binding to a strand of DNA. Benzopyrenes are mutagenic and highly carcinogenic - that is, they cause mutations and cancer. They result from the combustion of organic material - common carcinogenic routes being burning fossil fuels or smoking tobacco. As a mutagen it binds to, and alters the chemical structure of, DNA.
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.
