Probing the rice Rubisco–Rubisco activase interaction via subunit heterooligomerization [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2019 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

Molecular mechanism of Rubisco activase: Dynamic assembly and Rubisco remodeling. [PDF]
Front Mol Biosci, 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

The relative abundance of wheat Rubisco activase isoforms is post-transcriptionally regulated. [PDF]
Photosynth Res, 2021 Diurnal rhythms and light availability affect transcription–translation feedback loops that regulate the synthesis of photosynthetic proteins. The CO2-fixing enzyme Rubisco is the most abundant protein in the leaves of major crop species and its activity

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 ...
