High temperature enhances inhibitor production but reduces fallover in tobacco Rubisco
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]
