Abstract

Glycidate (2,3-epoxypropionate) stimulated CO(2) fixation in isolated spinach chloroplasts up to 100%. In the presence of glycidate the initial lag phase was abolished and the chloroplasts exported mainly 3-phosphoglycerate instead of dihydroxyacetone phosphate.Glycolate formation was not inhibited by glycidate, which is in agreement with the observation that preactivated ribulose-1,5-bisphosphate oxygenase is not inhibited by this compound. Furthermore, glycidate had no effect on electron transport (NADP reduction) and photophosphorylation, nor was a change in the coupling ratio observed.

摘要

缩水甘油酸（2,3-环氧丙酸）可使离体菠菜叶绿体中的二氧化碳固定率提高达100%。在缩水甘油酸存在的情况下，初始延迟期消失，叶绿体主要输出3-磷酸甘油酸而非磷酸二羟丙酮。缩水甘油酸并不抑制乙醇酸的形成，这与预激活的核酮糖-1,5-二磷酸加氧酶不受该化合物抑制的观察结果一致。此外，缩水甘油酸对电子传递（NADP还原）和光合磷酸化没有影响，也未观察到偶联率的变化。
