Project Summary

This team comprises faculty from SLAC, the School of Medicine, the School of Engineering and the School of Earth, Energy & Environmental Sciences. The researchers plan to develop a bioreactor of immobilized, engineered enzymes to efficiently convert CO2 into organic compounds like new biofuels. To do this, they will produce three-dimensional structural details of key carbon-fixation enzymes and engineer an improved set of enzymes for faster, more energy-efficient reactions.
