Molecular mechanism of Rubisco activase: Dynamic assembly and Rubisco remodeling [PDF]
Ribulose-1,5-bisphosphate (RuBP) carboxylase-oxygenase (Rubisco) enzyme is the limiting step of photosynthetic carbon fixation, and its activation is regulated by its co-evolved chaperone, Rubisco activase (Rca). Rca removes the intrinsic sugar phosphate

Probing the rice Rubisco-Rubisco activase interaction via subunit heterooligomerization. [PDF]
During photosynthesis the AAA+ protein and essential molecular chaperone Rubisco activase (Rca) constantly remodels inhibited active sites of the CO 2 -fixing enzyme Rubisco (ribulose 1,5-bisphosphate carboxylase/oxygenase) to release tightly bound sugar phosphates. Higher plant Rca is a crop improvement target, but

Rubisco activase requires residues in the large subunit N terminus to remodel inhibited plant Rubisco. [PDF]
ABSTRACTThe photosynthetic CO2fixing enzyme ribulose 1,5-bisphosphate carboxylase/oxygenase (Rubisco) forms inhibited complexes with multiple sugar phosphates, including its substrate ribulose 1,5-bisphosphate. At least three classes of ATPases associated with diverse cellular activities (AAA+ proteins) termed Rubisco activases (Rcas) have evolved to ...

Genetic determinants controlling maize rubisco activase gene expression and a comparison with rice counterparts [PDF]
Background Rubisco activase (RCA) regulates the activity of Rubisco and is a key enzyme of photosynthesis. RCA expression was widely reported to affect plant photosynthesis and crop yield, but the molecular basis of natural variation in RCA expression in

Identification of two bZIP transcription factors interacting with the promoter of soybean Rubisco activase gene (GmRCAα) [PDF]
Rubisco activase (RCA), a key photosynthetic protein, catalyses the activation of Rubisco and thus plays an important role in photosynthesis. Although the RCA gene has been characterized in a variety of species, the molecular mechanism regulating its ...

Immunogold localization of Rubisco and Rubisco activase in leaves of rice
The enzymes of Rubisco and Rubisco activase were localized using immunogold-labeled method and electron microscope techniques. The results showed that Rubisco was mainly located in choloroplast, Rubisco activase, however, specially labeled both in ...

The plastid casein kinase 2 phosphorylates Rubisco activase at the Thr-78 site but is not essential for regulation of Rubisco activation state [PDF]
Rubisco activase (RCA) is essential for the activation of Rubisco, the carboxylating enzyme of photosynthesis. In Arabidopsis, RCA is composed of a large RCAα and small RCAβ isoform that are formed by alternative splicing of a single gene (At2g39730 ...

Down‐regulation of wheat Rubisco activase isoforms expression by virus‐induced gene silencing [PDF]
Rubisco activase (Rca) is an essential photosynthetic enzyme that removes inhibitors from the catalytic sites of the carboxylating enzyme Rubisco. In wheat, Rca is composed of one longer 46 kDa α‐isoform and two shorter 42 kDa β‐isoforms encoded by the ...
