Regulatory Phosphorylation Cycles During C4-Photosynthesis

该项目涉及碳的光调节- 光合作用过程中的固定酶;两种关键酶-- 一个在细胞质中，另一个在叶绿体中， 通过可逆磷酸化的翻译后修饰， 也是计划研究的重点。 详细生化 体内磷酸化事件的检查是 项目，而第二部分将集中在一个明显的光- 调节蛋白质周转。 光合事件的调节 当这些研究的结果 是可用的，因为他们将提供扩大的见解， 叶绿体和细胞质的可逆磷酸化过程 在植物中。 这三年，更新项目的重点是分析 C-4中两种关键酶的可逆光活化 植物的光合作用 预计结果将提供 本条例的重要细节，因为它是由 细胞质和叶绿体中的可逆磷酸化 植物。 //

This project is concerned with the photoregulation of carbon- fixation enzymes in the photosynthetic process; two key enzymes-- one in the cytoplasm, the other in the chloroplast--are subject to post-translational modification by reversible phosphorylation(s), and are the focus of the research planned. Detailed biochemical examination of in vivo phosphorylation events is one part of the project, while a second part will be focused on an apparent light- modulated protein turnover. Regulation of photosynthetic events will be understood much better when the results of these studies are available, for they will provide enlarged insights into both chloroplastic and cytoplasmic, reversible phosphorylation processes in plants. This three year, renewal project is focused on analysis of the reversible light activation of two key enzymes involved in C-4 photosynthesis in plants. The results can be expected to provide important details of this regulation as it is effected by reversible phosphorylation in both the cytoplasm and chloroplasts of plants. //
