WebMechanisms of Enzyme Induction. Enzyme induction is mediated through the binding of one or more chemical activators to CYP isozyme intracellular receptors, ultimately producing increased transcription of CYP genes. This ligand-activated transcription results in translation of messenger RNA (mRNA) leading to increased synthesis of the CYP protein.
