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
\
Proteasomes are large molecular machines that degrade unneeded or damaged proteins that have been tagged with polyubiquitin.
Neurotoxin concept Neurotoxin of type A of bacterium Clostridium botulinum which causes food intoxication botulism, molecular model 3d rendering
Gamma secretase protein complex. Multi-subunit intramembrane protease that plays role in processing of proteins. 3D illustration.
Colorful chain of amino acids or bio molecule called proteins - 3d illustration
A ball and stick model of Human Insulin. Isolated on black.
3d rendering of ubiquitin is attached to target proteins by a process called ubiquitination
3D cartoon and Gaussian surface models. PDB 3kqg, chain id color scheme, white background.
DNA A-T Pair
Avibactam is a diazobicyclooctane inhibitor of gram-negative and gram-positive bacteria. Avibactam (red) inhibits the bacterial enzyme beta-lactamase (blue) of Clostridioides difficile.
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.
Ivermectin 3d rendering. Ivermectin is used to treat human diseases caused by roundworms and ectoparasites. PDB: 3RHW
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.
The DNA tetrahedron is designed to be mechanically robust; it consists of rigid triangles of DNA helices covalently joined at the vertices
3D cartoon and Gaussian surface models, chain id color scheme, PDB 5y0m, white background
Molecular model of Thymine, 1 of 4 nucleobases to form DNA
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.
3d rendered Gastric inhibitory polypeptide (GIP, glucose-dependent insulinotropic peptide) endocrine protein hormone, 3D illustration
Indoleamine 2,3 dioxygenase 1 (IDO1) protein. Tryptophan catabolic enzyme of the kynurenine pathway. 3D illustration.
Rendering of the atomic structure of an antibody variable region.
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.
Conjugal of DNA to primary antibodies with protein G and linker for multiplexed cellular targeting: 3D rendering
3D cartoon and Gaussian surface models, PDB 1j7n, chain id color scheme, white background
Passive immunization with nanobodies: three neutralizing nanobodies (blue) bound to the receptor-binding domain of the omikron SARS-CoV-2 spike protein. Nanobodies can have a highly increased neutralizing activity compared to antibodies.
