Enzymes synthesized via translational processes often exist initially in a functionally inactive state known as zymogens or proenzymes, requiring specific post-translational modifications such as peptide cleavage for activation within biochemistry and molecular biology domains. This concept relies on the theoretical distinction between apoenzymes (protein components) and cofactors—comprising organic coenzymes derived from vitamins and inorganic activators like metal ions—which bind to form a catalytically active holoenzyme complex. The principle establishes that enzymatic function is strictly contingent upon both structural maturation of the protein substrate and the presence of essential non-protein factors, thereby defining the biochemical necessity for activation sequences and auxiliary molecules to mediate chemical reactions.
