Rubisco与Rubisco活化酶的分子机理研究进展

Advances in Molecular Mechanisms of Rubisco and Rubisco Activase

核酮糖-1,5-二磷酸羧化酶/加氧酶(Rubisco)首先作为植物光合作用反应固定CO_2的关键酶,而且还参与光呼吸途径,消耗了光合产物,光呼吸造成净光合效率可达50%的损失,Rubisco作用机理对提高植物的光合效率至关重要。自从Calvin等(1953)通过研究光合碳循环首次证明了Rubisco的存在,目前已对其的分布、三级结构、类型以及功能等均有了深入地认识。本研究就Rubisco的结构、功能、分布和性质等以及其活化酶的分子机理的研究进展作了介绍,并对其未来的研究方向做了展望。

Ribulose-1,5-bisphosphate carboxylase/oxygenase（Rubisco） is the process of photosynthesis CO_2 fixation of a key enzyme, is also involved in photorespiration metabolic pathways of plants, which consume organic compounds synthesized by plant photosynthesis thus resulting in the loss of net photosynthetic efficiency up to 50%. Therefore, the study of photosynthesis, Rubisco to improve the efficiency of the plant has a very important significance. In addition, since 1953 Calvin and other photosynthetic carbon cycle research confirmed the presence of Rubisco, Rubisco series of related issues and continue to be elucidated, a deeper understanding of their distribution, structure, type and function, and many other aspects of this article progress on Rubisco introduced the structure, function, distribution, properties and other research and made the prospect of Rubisco in the future.
