C1 - Cx Synthetic Biology
The regulation mechanisms and re-design of C1-Cx carbon metabolism network are the core scientific questions of this research. C1-Cx metabolism governs the most basic bioreactions for material and energy transformations and is nested in a complex network. We aim at a system-level understanding and re-design of it through quantification and modeling, and develop next-generation bioprocesses for synthesizing basic chemicals, amino acids, and future food (proteins) based on air (CO2, N2), water, and regenerative energy (light and electricity), contributing thus to carbon neutrality.
C1-Cx metabolism is also involved in many diseases, such as cancer and neurodegeneration. The quantitative and system-level study of C1-Cx metabolism is expected to provide new targets for their diagnosis and cure.
