Biophysical characterization of higher plant Rubisco activase.
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). Mechanistic and structural investigations of Rca have been hampered by its exceptional thermolability, high deg...
متن کاملRubisco, Rubisco activase, and global climate change.
Global warming and the rise in atmospheric CO(2) will increase the operating temperature of leaves in coming decades, often well above the thermal optimum for photosynthesis. Presently, there is controversy over the limiting processes controlling photosynthesis at elevated temperature. Leading models propose that the reduction in photosynthesis at elevated temperature is a function of either de...
متن کاملScanning of Transposable Elements and Analyzing Expression of Transposase Genes of Sweet Potato [Ipomoea batatas]
BACKGROUND Transposable elements (TEs) are the most abundant genomic components in eukaryotes and affect the genome by their replications and movements to generate genetic plasticity. Sweet potato performs asexual reproduction generally and the TEs may be an important genetic factor for genome reorganization. Complete identification of TEs is essential for the study of genome evolution. However...
متن کاملExpression quantitative trait loci analysis of two genes encoding rubisco activase in soybean.
Rubisco activase (RCA) catalyzes the activation of Rubisco in vivo and plays a crucial role in photosynthesis. However, until now, little was known about the molecular genetics of RCA in soybean (Glycine max), one of the most important legume crops. Here, we cloned and characterized two genes encoding the longer alpha -isoform and the shorter beta -isoform of soybean RCA (GmRCA alpha and GmRCA ...
متن کاملIn Vitro Characterization of Thermostable CAM Rubisco Activase Reveals a Rubisco Interacting Surface Loop.
To maintain metabolic flux through the Calvin-Benson-Bassham cycle in higher plants, dead-end inhibited complexes of Rubisco must constantly be engaged and remodeled by the molecular chaperone Rubisco activase (Rca). In C3 plants, the thermolability of Rca is responsible for the deactivation of Rubisco and reduction of photosynthesis at moderately elevated temperatures. We reasoned that crassul...
