Interactions of ATP, ADP and magnesium ion with rubisco activase and their effects on rubisco activation

open access: yes, 1992
Rubisco activase is a chloroplast protein that mediates a greatly enhanced activation of rubisco in the presence of ATP and Mg$\sp{2+}$. The fluorescent dye 1-anilinonaphthalene-8-sulfonate was used to study the binding of rubisco activase with ligands ...

Expression of the genes encoding rubisco and rubisco activase in cucumber leaves

open access: yesAFRICAN JOURNAL OF AGRICULTURAL RESEEARCH, 2012
Diurnal changes in the gene expressions and activities of Rubisco and Rubisco activase (RCA) in different position of leaves of cucumber were investigated. The results showed the diurnal variations of the mRNA abundance of rbcL, activities of Rubisco and RCA in 4th apical leaf which gave a single-peak curve, which was similar to the Pn curve on a sunny

Limited Proteolysis of the AAA+ Protein Rubisco Activase from Nicotiana tabacum [PDF]

open access: yes, 2012
: Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) is widely accepted as the world's most abundant enzyme and represents the primary entry point for inorganic carbon into the biosphere.

Identifying the Rubisco Recognition Domain and Critical Arginines in Activase and Engineering Activase With Improved Thermostability for Arabidopsis

open access: yes, 2006
Heat sensitivity of Rubisco activase(s) confers a major limitation on leaf photosynthesis at moderately high temperature in Arabidopsis. To overcome this limitation, a thermostable activase for Arabidopsis was generated by engineering the more ...

The effects of Rubisco activase on C4 photosynthesis and metabolism at high temperature

open access: yes, 2015
The activation of Rubisco in vivo requires the presence of the regulatory protein Rubisco activase. This enzyme facilitates the release of sugar phosphate inhibitors from Rubisco catalytic sites thereby influencing carbamylation.

Can negligible levels of Rubisco activase, be the reason for decreased rubisco activity levels in guard cells?

open access: yes, 2001
Rubisco in guard cell chloroplasts has been a subject of controversy for decades. Several studies have unequivocally confirmed not only the presence of Rubisco in guard cells but also found it to be catalytically active. Based on a cell basis, the amount

Changes in PEP Carboxylase, Rubisco and Rubisco activase mRNA levels from maize (Zea mays) exposed to a chronic ozone stress

open access: yes, 2007
We quantified the ozone impact on levels of Zea mays L. cv. Chambord mRNAs encoding C4-phosphoenolpyruvate carboxylase (C4-PEPc), ribulose-l,5-bisphosphate carboxylase/oxygenase small and large subunits (Rubisco-SSU and Rubisco-LSU, respectively) and ...

Purification of Rubisco activase from leaves or after expression in Escherichia coli

open access: yes, 2011
Rubisco activase is a molecular chaperone that modulates the activation state of Rubisco by catalyzing the ATP-dependent removal of tightly-bound inhibitory sugar-phosphates from Rubisco's catalytic sites.
