Back to the future of photosynthesis

The central biocatalyst in photosynthesis, Rubisco, is the most abundant enzyme on earth. But how did Rubisco evolve, and how did it adapt to environmental changes during Earth’s history? By reconstructing billion-year-old enzymes, our team has deciphered one of the key adaptations of early photosynthesis. Our results not only provide insights into the evolution of modern photosynthesis but also offer new synthetic impulses for improving it.
