by which the synthesis of an enzyme is prevented by repressor
molecules. In many cases, the end product of a synthesis chain (e.g. an amino acid)
acts as a feed-back corepressor by combining with an intracellular aporepressor protein,
so that this complex is able to block
the function of an operator. As a result, the whole operon
is prevented from being transcribed into mRNA
, and the expression of all enzymes
necessary for the synthesis of the end product amino acid is abolished.
