Preferred Label : enzyme repression;
IUPAC acronym : mRNA;
IUPAC definition : The mode 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.;
