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. 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 glucagon.[1][2] Image File history File links Download high-resolution version (1002x855, 706 KB)By Richard Wheeler (Zephyris) 2006. ...

The enzyme, either by itself or in connection with a second enzyme, catalyzes the formation of an activated conjugate which then is deposited wherever a receptor for the activated conjugate is immobilized.
One of the unique features of this invention is the analyte dependent enzymeactivation system which catalyzes deposition of conjugate by converting the substrate portion of the conjugate to an activated form which is deposited wherever a specific receptor for the activated conjugate is immobilized.
Other important factors include availability of the enzyme or enzymes, relative ease or difficulty of coupling it to the member of a specific binding pair, stability of the enzyme or enzymes as well as the stability of the conjugate and the receptor.
