réaction multi-enzymatique

CONT: L'immobilisation de cellules présente l'avantage de permettre la réalisation de réactions multi-enzymatiques assurant la régénération de cofacteurs.

CONT: The first step in a multienzyme reaction sequence, i.e., the step catalyzed by the allosteric enzyme, is usually irreversible under intracellular conditions. It is often called the committing reaction; once it occurs, all the ensuing reactions of the sequence take place. Clearly, it is good strategy for the cell to regulate a metabolic pathway at its first step, to achieve maximum economy of metabolites.
