Molecular mechanism of Rubisco activase: Dynamic assembly and Rubisco remodeling [PDF]
Frontiers in Molecular Biosciences, 2023 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

Down‐regulation of wheat Rubisco activase isoforms expression by virus‐induced gene silencing [PDF]
Plant DirectRubisco 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 ...

Probing the rice Rubisco-Rubisco activase interaction via subunit heterooligomerization. [PDF]
Proc Natl Acad Sci U S A, 2019 Significance All plant-based biomass production, and thus our food supply, depends on the slow and inaccurate catalyst Rubisco to transform gaseous carbon dioxide into organic molecules. Rubisco requires a metabolic repair enzyme, Rubisco activase, which

Insights into the mechanism and regulation of the CbbQO-type Rubisco activase, a MoxR AAA+ ATPase. [PDF]
Proc Natl Acad Sci U S A, 2020 Significance Life depends on the ability of organisms such as plants to convert the gas carbon dioxide into sugar molecules to produce energy and build biomass. Most of this activity is catalyzed by the CO2-fixing enzyme Rubisco.

Identification of two bZIP transcription factors interacting with the promoter of soybean Rubisco activase gene (GmRCAα) [PDF]
Frontiers in Plant Science, 2016 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 ...

In vivo evidence for a regulatory role of phosphorylation of Arabidopsis Rubisco activase at the Thr78 site. [PDF]
Proc Natl Acad Sci U S A, 2019 Significance Rubisco activase (Rca) regulates the activation state of Rubisco, the carboxylating enzyme of photosynthesis. Regulation of Rca by redox status of cysteine residues in species such as Arabidopsis is well recognized, but the role of recently ...
