Allosteric enzymes are the enzymes which can exist in "Allo" or more than one different "steric" states. The molecules which cause a shift in steric structure are called as modulators. Allosteric behavior itself was often observed for regulatory or control enzymes of metabolic pathways and forms the basis for feedback inhibition and activation. Such enzymes were called as allosteric by Jacob and Monod.
