Physical interaction and activity coupling between two enzymes induced by immobilization of one.
Flavin reductase and bacterial luciferase are believed to be coupled in the in vivo light emitting reaction. In extracts, however, they are both soluble enzymes that exhibit little or no association. Immobilized luciferase, covalently attached to Sepharose, was found to bind the soluble reductase and to exhibit activity in the coupled reaction reaction with an enhanced efficiency of electron transfer.
