an outlook on 'second generation enzyme technology ' , which involves immobilized multi-enzyme systems and coenzymes , is given with examples : the immobilization of dehydrogenases with their active sites facing one another , and systems containing nad ( h ) coenzymes immobilized by coupling to dextran ( in an enzyme electrode ) , to polyethylene glycol ( in a membrane reactor ) , or to enzymes themselves .
