Regulatory enzymes

Regulatory enzymes

A regulatory enzyme is an enzyme in a biochemical pathway which, through its responses to the presence of certain other biomolecules, regulates the pathway's activity. This is usually done for pathways whose products may be needed in different amounts at different times, such as hormone production. Regulatory enzymes exist at high concentrations (low Vmax) so its activity can be increased or decreased with changes in substrate concentrations.

Regulatory enzymes are of two types:Allosteric enzymes and covalently modulated enzymes.
