“This de-mixing of proteins is called phase separation, a process that concentrates proteins locally. The interaction between CcmM and Rubisco causes de-mixing of the protein complex from other proteins in the cell. Using cryo-EM, the researchers showed that CcmM does not replace the small subunit of Rubisco but rather links Rubisco proteins together by an unexpected mechanism. “In this study, we took advantage of the rapidly developing method of cryo-electron microscopy to capture these dynamic interactions”, says Huping Wang, shared first author of the study. However, the complex between CcmM and Rubisco is highly dynamic and therefore could not be solved by traditional structural biology methods. CcmM is built of several repeat modules that resemble the small subunit of Rubisco – therefore it was long assumed that these modules replace the small subunits of Rubisco when the proteins interact, thereby linking Rubisco proteins. The new study has now demonstrated how the formation of carboxysomes is initiated.Ĭyanobacteria use a helper protein called CcmM to capture Rubisco. In this way, cyanobacteria reduce the energy that is lost in the side reaction with oxygen. Cyanobacteria locally increase the concentration of CO 2 in specialized structures called carboxysomes and confine their Rubisco to these structures. They have evolved a strategy to increase the efficiency of their Rubisco enzyme. A team led by Manajit Hayer-Hartl, head of the research group “Chaperonin-assisted protein folding” at the Max Planck Institute of Biochemistry in Martinsried, has now made an important contribution to these efforts.Ĭyanobacteria are aquatic microbes that perform photosynthesis. Therefore, scientists are trying to engineer a more efficient version of Rubisco to improve plant growth. A lot of energy is lost in this side reaction. Instead of binding CO 2, Rubisco can also react with oxygen. However, Rubisco, which is estimated to be the most abundant enzyme on Earth, works slowly and inefficiently. The critical enzyme of this reaction is Rubisco, which catalyzes the fixation of CO 2 from the atmosphere. In a process called photosynthesis, they convert water and carbon dioxide (CO 2) to sugar and oxygen with the help of sunlight. While most organisms have to take up nutrients to generate energy for their cells, plants and some microbes can fuel their cells with light energy. Photosynthesis – essential but inefficient To meet this demand, scientists are working on strategies to improve the productivity of crops. With the global population increasing by an estimated 80 million people each year, the demand for food is steadily on the rise.
