Interpretive Summary: Technical Abstract: Rubisco activase is a protein that is required in higher-plants to maintain and regulate the activity of Rubisco, the protein formally known as ribulose 1,5-bisphosphate carboxylase/oxygenase. Rubisco is a very important protein in photosynthesis because it initiates both photosynthetic carbon metabolism via its carboxylase activity and photorespiration via its oxygenase activity (1). The activity of Rubisco is a major factor limiting photosynthesis and thus the productivity of many of our major crops. The properties of Rubisco activase and the current understanding of the regulation of Rubisco by the activase will be discussed. |
