Cyanobacteria are important contributors to global photosynthesis and have evolved unique mechanisms for capturing CO2 from their aquatic environments. Understanding these molecular mechanisms is important for both predicting how cyanobacteria affect carbon fixation at the global scale, and how their genetic specialisation may be used for improving photosynthesis in agricultural plants. This project aims to examine one particular aspect of this specialisation, the multi-protein carboxysome complex, where CO2 fixation occurs. Using recent whole-genome information we will take a proteogenomic approach to understanding the structure and function of the carboxysome and how it contributes to the photosynthesis of the cell.

蓝细菌是全球光合作用的重要贡献者，并已进化出独特的机制，从其水生环境中捕获CO2。了解这些分子机制对于预测蓝藻如何在全球范围内影响碳固定以及它们的遗传特化如何用于改善农业植物的光合作用都很重要。该项目旨在研究这种专业化的一个特定方面，即多蛋白质羧基复合物，其中发生CO2固定。利用最近的全基因组信息，我们将采取蛋白质基因组学的方法来理解的结构和功能的羧基，以及它如何有助于光合作用的细胞。
