This footage shows the translation initiation complex, which consists of the ribosomal small subunit, transfer RNA (tRNA), and translation initiation factors. The golden ribbon represents the RNA.
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.
Gamma secretase protein complex. Multi-subunit intramembrane protease that plays role in processing of proteins. 3D illustration.
Structure of novel coronavirus spike receptor-binding domain (pink) complexed with its receptor ACE2 (blue), surface modeel, 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.
Molecular Model of Cyclosporine, an immunosuppressant drug widely used in organ transplantation to prevent rejection.
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.
Indoleamine 2,3 dioxygenase 1 (IDO1) protein. Tryptophan catabolic enzyme of the kynurenine pathway. 3D illustration.

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 lactose, a disaccharide sugar in milk.
A 3D rendering of a SpyTag-SpyCatcher complex with antibody molecule in the white background
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.
Botulinum toxin neurotoxic protein, 3D rendering. Produced by Clostridium botulinum. Cosmetically used to treat wrinkles.
