Allosteric regulation - Wikipedia
https://en.wikipedia.org/wiki/Allosteric_regulation

In biochemistry, allosteric regulation (or allosteric control) is the regulation of an enzyme by binding an effector molecule at a site other than the enzyme's active site.. The site to which the effector binds is termed the allosteric site or regulatory site.Allosteric sites allow effectors to bind to the protein, often resulting in a conformational change involving protein dynamics.
