The interaction changes the shape of the enzyme, thus affecting the active site of the usual complex between the enzyme and its substrate (the substance on which the enzyme acts). As a result, the enzyme's ability to catalyze a reaction (see catalysis)is either inhibited or enhanced . If the regulatory molecule inhibits an enzyme in the pathway of its own synthesis, the control is said to be feedback inhibition. Allosteric control enables the cell to regulate needed substances rapidly.

这种相互作用改变了的形状,于是影响了通常与它的基底(在这种物质上面起作用)之间复合物的活动位置。结果,使催化反应的能力或是抑制,或是增强。如果调节分子在它自己合成的途中抑制了,这种控制称为反馈抑制。变构调控使细胞能迅速地调节所需物质的合成。
