3D cartoon and Gaussian surface models, chain id color scheme, PDB 5y0m, white background
Gamma secretase protein complex. Multi-subunit intramembrane protease that plays role in processing of proteins. 3D illustration.
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.
Nirmatrelvir inhibits the 3C-like protease of the SARS-CoV 2 virus. The coronavirus 3CL hydrolase enzyme, also known as the main protease, is essential for the maturation of the virus.
DNA A-T Pair
Cytochrome P450 molecule. CYP 3A4 is the most promiscuous of the human CYP enzymes. Molecular model. 3D rendering. Illustration
Abstract geometric shape
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.
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.
Recombinant human insulin. 3d cartoon model based on protein data bank
Avibactam is a diazobicyclooctane inhibitor of gram-negative and gram-positive bacteria.  Avibactam (red) inhibits the bacterial enzyme beta-lactamase (blue) of Clostridioides difficile.
Molecular Model of Human Insulin with disulfide bonds shown.
Isolated Proteasome with protein conjugated with ubiquitin 3d rendering
The crystal structure of the tumor marker protein. The 3D model of the biological macromolecule.
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.
3D cartoon and Gaussian surface models, chain id color scheme, PDB 4ci9, white background
Interleukin 13 (IL-13) cytokine protein. 3D illustration. Cartoon representation combined with semi-transparent surfaces.
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.
Aztreonam (left, orange) inhibits the beta-lactamase from Acinetobacter species. Avibactam (red) inhibits the beta-lactamase (blue) of Clostridioides difficile.
Molecular Model of Infliximab, or Remicade, a monoclonal antibody against tumour necrosis factor alpha (TNF-α), which is used to treat autoimmune diseases
Human alcohol dehydrogenase (ADH1A) protein model
3D model of a protein molecule. The spatial oriented structure of the macromolecule.
A model of a transcription factor binding to a strand of DNA. Transcription factors are proteins which bind to specific sequences of DNA, enabling and controlling the copying of genetic data.
3D cartoon and Gaussian surface models, PDB 3hg3, white background
Glucose-6-phosphate dehydrogenase (G6PD) protein. Enzyme of the pentose phosphate pathway that generates co-enzyme NADPH. 3D illustration.
Apolipoprotein D, a protein mainly produced in the brain and testes.  A biomarker of androgen insensitivity syndrome. 3d rendering.
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 Human Insulin with disulfide bonds shown.
