The regulation of Rubisco by Rubisco activase
Journal of Experimental Botany, 1995Abstract The activity of Rubisco depends on the conversion of the inactive form (E) to the active form (ECM); the binding of the inhibitors CA1P and RuBP to ECM and E, respectively; and the catalytic formation of inhibitory sugar bisphosphates from the enediol intermediate that precedes carboxylation/oxygenation.

Heat sensitivity of Rubisco, Rubisco activase and Rubisco binding protein in higher plants
Acta Physiologiae Plantarum, 2004 During the past few years the investigations concerning Rubisco and the changes of its activity and properties at elevated temperature were reconsidered with special reference to the important role of Rubisco activase and Rubisco binding protein. The major changes in Rubisco, Rubisco activase and Rubisco binding protein reported recently are presented ...

The activity of Rubisco’s molecular chaperone, Rubisco activase, in leaf extracts
Photosynthesis Research, 2011 Rubisco frequently undergoes unproductive interactions with its sugar-phosphate substrate that stabilize active sites in an inactive conformation. Restoring catalytic competence to these sites requires the "molecular chiropractic" activity of Rubisco activase (activase).

Plant, Cell &Environment, EarlyView.Rubisco activase mediates the activation of Rubisco, the key photosynthetic CO2-fixing enzyme, and plays a crucial role in regulating photosynthesis and plant growth. Rubisco activase restores catalytic competence to Rubisco active sites by promoting the

Rubisco's chiropractor: a study of higher plant Rubisco activase [PDF]
, 2015 Rubisco activase operates as the chaperone responsible for maintaining the catalytic competency of Ribulose 1,5-bisphophate carboxylase oxygenase (Rubisco) in plants. Rubisco is notoriously inefficient, rapidly self-inactivating under physiological conditions. Rubisco activase uses the power released from the hydrolysis of ATP to power a conformational

Recent developments in the engineering of Rubisco activase for enhanced crop yield.
Biochemical Society Transactions, 2023Rubisco activase (RCA) catalyzes the release of inhibitory sugar phosphates from ribulose-1,6-biphosphate carboxylase/oxygenase (Rubisco) and can play an important role in biochemical limitations of photosynthesis under dynamic light and elevated ...

The world's population may reach 10 billion by 2050, but 10% still suffer from food shortages. At the same time, global warming threatens food security by decreasing crop yields, so it is necessary to develop crops with enhanced resistance to high ...

Exploring Genetic Diversity in Rubisco Activase [PDF]
, 2023 Via photosynthesis, plants are the most important point of entry for energy into the biosphere. The Calvin-Benson-Bassham cycle is the part of the photosynthetic process responsible for carbon assimilation, which is done by Rubisco. Rubisco activase (Rca) acts as an activator of Rubisco, removing inhibitory sugar phosphates.
