Allosteric Enzyme Definition:

  • An enzyme whose activity is altered by the non covalent binding of a small effector (allosteric effector) at a regulatory site separate from the catalytic site; effector binding causes a conformational change in the enzyme's catalytic site, which leads to enzyme activation or inhibition.

Allosteric Enzyme Explanation:

Allosteric enzymes are those enzymes whose structure and function is altered after an effector molecule binds to them. This alteration in shape changes the binding affinity at the active site of the enzyme. Thus, this can lead to the inhibition or activation of an enzyme.
