apoenzyme
This term describes the inactive, protein-only component of a complex enzyme. It carries a technical, biochemical connotation of incompleteness, representing a structural scaffold that is functionally dormant until it pairs with a non-protein helper molecule.
In laboratory and academic settings, the word is used to distinguish the polypeptide chain from the holoenzyme, which is the fully functional, combined unit. It is a precise scientific term used exclusively in biochemistry and molecular biology.
Meanings
Examples
The apoenzyme is the inactive protein part of the enzyme.
Without its cofactor, the apoenzyme cannot catalyze the reaction.
I wonder if this specific apoenzyme requires a metal ion to function.
The researcher isolated the apoenzyme to study its folding properties.
Wait, so the apoenzyme becomes a holoenzyme once the coenzyme binds?
The binding site of the apoenzyme is highly specific to its cofactor.
An apoenzyme lacks the necessary non-protein component for activity.
We need to determine the concentration of the apoenzyme in the sample.
