  • Step 1 of 4
  • Step 2 of 4

    Allosteric enzymes are constructed from 2 or more polypeptidesubunits. Each subunit has its own active site.

    Allosteric enzyme possess additional sites known as “Allostericsites” besides active site

    Allosteric site, which is used for binding of an activator orinhibitor

  • Step 3 of 4

    Binding of an “activator” at allosteric site stabilizes theactive form of the enzyme

    The subunits of an allosteric enzyme fit together in such a waythat conformational change in one subunit alters the conformationof other subunits, when an activator binds. As a result, theallosteric enzymes become active.

  • Step 4 of 4

    Binding of an “inhibitor” at allosteric site destabilizes theactive form of the enzyme. Conformational change in one subunit,changes the conformation of other subunits when an inhibitor binds.Regulatory site affects the active sites of all subunits. As aresult, the allosteric enzyme becomes inactive
