Description
High temperature inhibits photosynthesis by several mechanisms including reduction in Rubisco activity. While the initial reaction velocity of purified, fully carbamylated, inhibitor-free Rubisco increases with temperature in vitro, over time, the reaction velocity slowly declines (fallover) because of the enzymatic and non-enzymatic production of inhibitors from the substrate ribulose-1,5-bisphosphate. We tested whether fallover could contribute to the decline in Rubisco activity observed in...[Show more]
