Large variation in the Rubisco kinetics of diatoms reveals diversity among their carbon-concentrating mechanisms
While marine phytoplankton rival plants in their contribution to global primary productivity, our understanding of their photosynthesis remains rudimentary. In particular, the kinetic diversity of the CO₂-fixing enzyme, Rubisco, in phytoplankton remains unknown. Here we quantify the maximum rates of carboxylation (Kcatᶜ), oxygenation (Kcatᵒ), Michaelis constants (K m) for CO₂ (K C) and O₂ (K O), and specificity for CO₂ over O₂ (SC/O) for Form I Rubisco from 11 diatom species. Diatom Rubisco...[Show more]
