Understanding Allosteric Sites
Allosteric sites are specific locations on an enzyme where molecules can bind, leading to changes in the enzyme's activity. When a compound binds to an allosteric site, it induces a conformational change in the enzyme, which can affect the active site where substrate binding occurs.
Role of Allosteric Sites
- Location: Allosteric sites are distinct from the active site where substrates bind.
- Functionality: When a compound occupies the allosteric site, it alters the shape of the enzyme, which can enhance or inhibit enzyme activity.
Mechanism of Action
- Conformational Change: Binding of an allosteric effector (the compound) causes a structural change in the enzyme.
- Impact on Active Site: This change can either increase the affinity of the enzyme for its substrate or decrease it, influencing the overall enzymatic reaction.
Types of Allosteric Regulation
- Positive Regulation: Some allosteric effectors increase enzyme activity, facilitating the binding of substrates.
- Negative Regulation: Others may inhibit activity, preventing substrate binding and thus decreasing the reaction rate.
Importance in Biochemical Pathways
- Regulation: Allosteric sites play a crucial role in metabolic pathways by allowing for fine-tuning of enzyme activity according to cellular conditions.
- Therapeutic Target: Many drugs are designed to target allosteric sites to modulate enzyme activity for therapeutic benefits.
In conclusion, the compound binding to site Y is classified as an allosteric site because it leads to a change in the shape of the active site, influencing enzymatic function.

When a drug binds to an enzyme from a site other than the active site, it is called an allosteric site. Binding to this site causes the change in shape of active site such that the substrate cannot recognise it.
