A ribbons model of Human Growth Hormone, also known as Somatotropin, with a translucent surface model.

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.

Gamma secretase protein complex. Multi-subunit intramembrane protease that plays role in processing of proteins. 3D illustration.

Rendered coronavirus/2019-nCoV single-stranded RNA, built from experimentally determined Ebola virus crystal structure. Color symbols - bluewhite=carbon, pink=oxygen, lightblue=nitrogen, white=hydrogen, lavender=phosphorus

3d rendering of ubiquitin is attached to target proteins by a process called ubiquitination

Neurotoxin concept Neurotoxin of type A of bacterium Clostridium botulinum which causes food intoxication botulism, molecular model 3d rendering

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.

3D cartoon and Gaussian surface models. PDB 2aai, white background.

Avibactam is a diazobicyclooctane inhibitor of gram-negative and gram-positive bacteria. Avibactam (red) inhibits the bacterial enzyme beta-lactamase (blue) of Clostridioides difficile.

DNA A-T Pair

c-Myc and Max transcription factors bound to DNA. 3D illustration. Atoms shown as spheres with conventional color coding.

Cytochrome P450 molecule. CYP 3A4 is the most promiscuous of the human CYP enzymes. Molecular model. 3D rendering. Illustration

Colorful chain of amino acids or bio molecule called proteins - 3d illustration

Cholera toxin, molecular model. Cholera toxin (choleragen) is a protein complex secreted by the bacterium Vibrio cholerae, that causes the disease cholera. It is made up of a wedge-shaped A subunit (right part of illustration) and five B subunits (left part of illustration) that form a ring which binds to the intestinal lining. In its most severe forms, cholera is one of the most rapidly fatal illnesses known.

A ball and stick model of Human Insulin. Isolated on black.

3D cartoon and Gaussian surface models, chain id color scheme, PDB 5y0m, 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.

Molecular model of Thymine, 1 of 4 nucleobases to form DNA

Glucose-6-phosphate dehydrogenase (G6PD) protein. Enzyme of the pentose phosphate pathway that generates co-enzyme NADPH. 3D illustration.

New variant of coronavirus, mutation in the virus's spike protein

Conjugal of DNA to primary antibodies with protein G and linker for multiplexed cellular targeting: 3D rendering

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.

3D cartoon and Gaussian surface models, chain id color scheme, PDB 4ci9, white background

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.

Model of human Insulin, a hormone to regulate carbohydrate and fat metabolism

Botulinum toxin neurotoxic protein, 3D rendering. Produced by Clostridium botulinum. Cosmetically used to treat wrinkles.
