What is allosteric regulation inhibition?

Posted April 4, 2024


Answer

Allosteric activation and inhibition refer to two main types of allosteric regulation, which involves the regulation of enzyme activity through the binding of an effector molecule at sites other than the enzyme's active site. 

Allosteric Inhibition: Allosteric inhibition occurs when a molecule binds to an allosteric site on the enzyme and hampers its activity. The inhibitor molecule induces a conformational change in the enzyme that decreases its affinity for the substrate. This leads to a decrease in enzyme activity and a reduced rate of the catalyzed reaction.

Allosteric inhibition is an important regulatory mechanism in cells, allowing for the modulation of metabolic pathways and enzyme functions in response to changing cellular conditions.
