Abstract:

The development of co-immobilized multi-enzymatic systems is increasingly driven by economic and environmental constraints that provide an impetus to develop alternatives to conventional multistep synthetic methods. As in nature, enzyme-based systems work cooperatively to direct the formation of desired products within the defined compartmentalization of a cell. In an attempt to mimic biology, co-immobilization is intended to immobilize a number of sequential or cooperating biocatalysts on the same support to impart stability and enhance reaction kinetics by optimizing catalytic turnover. There are three primary reasons for the utilization of co-immobilized enzymes to enhance the efficiency of one of the enzymes by the in-situ generation of its substrate, to amplify a process that is conventionally carried out in several steps andor to eliminate undesired by-products of an enzymatic reaction. As such, co-immobilization provides benefits that span numerous biotechnological applications , from biosensing of molecules to cofactor recycling and to combination of multiple biocatalysts for the synthesis of valuable products.
