Allosteric regulation refers to the process for modulating the activity of a protein by the binding of a ligand, called an effector, to a site topographically distinct from the site of the protein, called the active site, in which the activity characterizing the protein is carried out, whether catalytic (in the case of enzymes) or ...
Sigmoidal curves, allosteric - Big Chemical Encyclopedia
WebJun 10, 2024 · Allosteric enzymes often display sigmoidal plots of the reaction rate V0 versus substrate concentration [S], rather than the hyperbolic plots displayed by enzymes that do obey Michaelis-Menten kinetics. Allosteric enzymes often have multiple subunits each with an active site that binds and catalyses the reaction. WebAllosteric enzymes have the important task of making digestion easier. As they penetrate the nucleus of molecules, these enzymes have the power to intervene in the metabolism of the organism, so they have the ability to cause it to absorb and excrete according to the biochemical needs that arise. cms carve in program

Non-allosteric enzymes show a rectangular hyperbola type of curve when Vo versus [S] was plotted. Whereas allosteric enzymes show the sigmoidal curve. Allosteric enzymes consist of more than one subunits i.e., they are oligomeric.
