Evolution of Rubisco activase gene in plants

Plant Molecular Biology, 2017
Rubisco activase of plants evolved in a stepwise manner without losing its function to adapt to the major evolutionary events including endosymbiosis and land colonization. Rubisco activase is an essential enzyme for photosynthesis, which removes inhibitory sugar phosphates from the active sites of Rubisco, a process necessary for Rubisco activation ...

Structure ofArabidopsis thalianaRubisco activase

Acta Crystallographica Section D Biological Crystallography, 2015
The CO2-fixing enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) is inactivated by the formation of dead-end complexes with inhibitory sugar phosphates. In plants and green algae, the ATP-dependent motor protein Rubisco activase restores catalytic competence by facilitating conformational changes in Rubisco that promote the release of ...

Rubisco activase – Rubisco's catalytic chaperone

Photosynthesis Research, 2003
The current status of research on the structure, regulation, mechanism and importance of Rubisco activase is reviewed. The activase is now recognized to be a member of the AAA(+) family, whose members participate in macromolecular complexes that perform diverse chaperone-like functions.

Overexpression of the halophyte Suaeda salsa Rubisco activase gene SsRCA in Arabidopsis improves plant photosynthesis under salt-stressed conditions.

Journal of plant physiology
Rubisco activase (RCA) is the key regulatory enzyme in photosynthetic carbon assimilation that governs the activation state of Rubisco, which is the rate-limiting enzyme in CO2 fixation.

The α form of Rubisco Activase supports photosynthesis during heat stress in the absence of the β form in Setaria viridis.

Journal of Experimental Botany
Rubisco activase (RCA) facilitates the removal of inhibitors from the Rubisco active site and is essential for plant growth at atmospheric CO2. Here we report the phenotypes of gene edited RCA mutants in the C4 grass Setaria viridis, which has two forms ...

In silico perspectives on RuBisCo activase and its role in mangrove CO2 sequestration.

Functional Plant Biology
Blue carbon, or carbon fixation, can reduce global CO2 emissions through green ecosystems, whereas the capacity of mangroves to fix atmospheric CO2 is five times higher than tropical or terrestrial land plants.

Rice RuBisCO activase promotes the dark-induced leaf senescence by enhancing the degradation of filamentation temperature-sensitive H.

The Plant Journal
Leaf senescence is a complex process that is triggered by many developmental and environmental factors. However, the mechanisms regulating leaf senescence remain unclear.

Biophysical characterization of higher plant Rubisco activase

Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2013
Rubisco activase (Rca) is a chaperone-like protein of the AAA+ family, which uses mechano-chemical energy derived from ATP hydrolysis to release tightly bound inhibitors from the active site of the primary carbon fixing enzyme ribulose 1,5-bisphosphate oxygenase/carboxylase (Rubisco).

Adenosine triphosphate hydrolysis by purified rubisco activase

Archives of Biochemistry and Biophysics, 1989
Activation of ribulose bisphosphate carboxylase/oxygenase (rubisco) in vivo is mediated by a specific protein, rubisco activase. In vitro, activation of rubisco by rubisco activase is dependent on ATP and is inhibited by ADP. Purified rubisco activase hydrolyzed ATP with a specific activity of 1.5 mumol min-1 mg-1 protein, releasing approximately ...
