n.脱辅（基）酶；酶蛋白

An apoenzyme is an inactive form of an enzyme that lacks one or more cofactors or prosthetic groups.
The apoenzyme first binds to its coenzyme before it can catalyze the chemical reaction.
A key step in the activation process is the binding of a small molecule to the apoenzyme, forming an enzyme-substrate complex.
The apoenzyme undergoes a conformational change upon cofactor binding, enabling its catalytic activity.
The apoenzyme-receptor interaction is crucial for the proper functioning of many biological processes.
After the substrate binds to the apoenzyme, a series of allosteric events occur, activating the enzyme.
Inhibitors often target the apoenzyme, preventing the formation of the active enzyme.
Researchers study apoenzymes to understand the molecular mechanisms behind enzyme regulation.
The conversion of an apoenzyme to its active form is often facilitated by another enzyme called a kinase.
The presence of different apoenzyme isoforms allows cells to fine-tune their metabolic pathways according to cellular needs.
