Back to the future of photosynthesis.researchers has uncovered one of the key early photosynthesis adaptations by reconstructing billion-year-old enzymes. Their findings not only shed light on how modern photosynthesis evolved, but also provide new impulses for enhancing it.
A team from the Max Planck Institute for Terrestrial Microbiology in Marburg, Germany, in partnership with the University of Singapore, has now successfully resurrected and studied billion-year-old enzymes in the lab using a combination of computational and synthetic techniques.
The molecular determinants of increased CO2 specificity in Rubisco remain largely unknown. However, they are of great interest to researchers aiming to improve photosynthesis. Interestingly, those Rubiscos that show increased CO2 specificity recruited a novel protein component of unknown function. This component was suspected to be involved in increasing CO2 specificity, however, the true reason for its emergence remained difficult to determine because it already evolved billions of years ago.
