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.
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.

Glucose-6-phosphate dehydrogenase (G6PD) protein. Enzyme of the pentose phosphate pathway that generates co-enzyme NADPH. 3D illustration.
Conjugal of DNA to primary antibodies with protein G and linker for multiplexed cellular targeting: 3D rendering
Isolated on white. 3D Render.
Epidermal growth factor (EGF) activates the EGF receptor (EGFR), that builds a heterodimer with HER3. The signal transduction continues through GRB2/SOS, Ras, Raf/MEK and ERK, that will activate many processes in the cell. Dysregulation is linked to cancer progression
A ball and stick + ribbons model of Bowman-Birk Protease Inhibitor, more commonly abbreviated to BBI. It is used clinically to treat and help prevent cancer.
3D cartoon and Gaussian surface models, PDB 2e5d, white background
