Chemoautotrophy In Subzero Environments And The Potential For Cold-adapted Rubisco

The act of fixing inorganic carbon into the biosphere is largely facilitated by one enzyme, Rubisco. Beyond well-studied plants and cyanobacteria, many bacteria use Rubisco for chemolithoautotrophy in extreme environments […]

Photosynthesis on Earth: Evolution Of Increased Complexity And Specificity At The Dawn Of Form I Rubiscos

The evolution of ribulose-1,5-bisphosphate carboxylase/oxygenases (Rubiscos) that discriminate strongly between their substrate carbon dioxide and the undesired side substrate dioxygen was an important event for photosynthetic organisms adapting to an […]
