摘要：

We have discovered a multienzymatic complex in fresh young sugarcane leaves. Th is complex is constituted of three enzymes: PEPcase, NADP-MDH and malic enzyme. After successive molecular sieving chromatography, we have obtained a highly purified sample of the complex which has a molecular weight of 711 kDa. Its functional interest has been evaluated by comparing the kinetic properties of the enzymes in their free forms to those in their complexed form. We show that the association of the three enzymes leads to important changes in their respective kinetic properties. ((C) Academie des sciences / Elsevier, Paris.).
