Cytochrome P450 molecule. CYP 3A4 is the most promiscuous of the human CYP enzymes. Molecular model. 3D rendering. Illustration
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.
RNA polymerase (from yeast) is composed of several proteins. It unwinds DNA strands (violet) and builds RNA (red) out of the nucleotides uridine, adenosine, cytlidine and guanosine monophosphate. Source: PDB entry 1i6h

Indoleamine 2,3 dioxygenase 1 (IDO1) protein. Tryptophan catabolic enzyme of the kynurenine pathway. 3D illustration.
A ball and stick model of Human Insulin. Isolated on black.
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.
