Bacillus stearothermophilus phosphofructokinase. PDB 6PFK.
Enzyme activators are molecules that bind to enzymes and increase their activity. These molecules are often involved in the allosteric regulation of enzymes in the control of metabolism. In opposition to coenzymes, enzyme activators are inorganic compounds, while both coenzymes and activators are cofactors.[1]
An example of an enzyme activator working in this way is fructose 2,6-bisphosphate, which activates phosphofructokinase 1 and increases the rate of glycolysis in response to the hormone insulin.[2][3]
