The allosteric site is the portion of a substrate
which allows an allosteric inhibitor
to engage allosteric change
or allosteric interaction
with the molecule (as you can see, 'allosteric' is a rather important term for the whole process). Allosteric sites must be differently shaped from active site
s to make sure that the molecule is only modified and not activated.
Any and all non-active sites on a molecule are called allosteric sites.
