The plastid casein kinase 2 phosphorylates Rubisco activase at the Thr-78 site but is not essential for regulation of Rubisco activation state [PDF]
Frontiers in Plant Science, 2016 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 ...

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

Effects of Overproduction of Rubisco Activase on Rubisco Content in Transgenic Rice Grown at Different N Levels. [PDF]
Int J Mol Sci, 2020 It has been reported that overproduction of Rubisco activase (RCA) in rice (Oryza sativa L.) decreased Rubisco content, resulting in declining photosynthesis.

Rubisco activase requires residues in the large subunit N terminus to remodel inhibited plant Rubisco. [PDF]
J Biol Chem, 2020 The photosynthetic CO2 fixing enzyme ribulose 1,5-bisphosphate carboxylase/oxygenase (Rubisco) forms dead-end inhibited complexes while binding multiple sugar phosphates, including its substrate ribulose 1,5-bisphosphate. Rubisco can be rescued from this

A role for differential Rubisco activase isoform expression in C4 bioenergy grasses at high temperature [PDF]
, 2020 Rubisco activase (Rca) facilitates the release of sugar‐phosphate inhibitors at Rubisco catalytic sites during CO2 fixation. Most plant species express two Rca isoforms, the larger Rca‐α and the shorter Rca‐β, either by alternative splicing from a single

Molecular adaptation during adaptive radiation in the Hawaiian endemic genus Schiedea. [PDF]
PLoS ONE, 2006 Background"Explosive" adaptive radiations on islands remain one of the most puzzling evolutionary phenomena. The rate of phenotypic and ecological adaptations is extremely fast during such events, suggesting that many genes may be under fairly strong ...

Effects of overexpression of the Rubisco small subunit gene under the control of the Rubisco activase promoter on Rubisco contents of rice leaves at different positions [PDF]
Soil science and plant nutrition (Tokyo), 2020 Photosynthetic activity is expected to be maintained during leaf senescence if the amount of Rubisco is maintained. As the mRNA level of the Rubisco gene decreases rapidly just before the stage of full expansion, its overexpression after full expansion ...

Dual Role of a Rubisco Activase in Metabolic Repair and Carboxysome Organization
bioRxiv, 2020 Rubisco, the key enzyme of CO2 fixation in photosynthesis, is prone to inactivation by inhibitory sugar phosphates. Inhibited Rubisco undergoes conformational repair by the hexameric AAA+ chaperone Rubisco activase (Rca) in a process that is not well ...

A Thermotolerant Variant of Rubisco Activase From a Wild Relative Improves Growth and Seed Yield in Rice Under Heat Stress. [PDF]
Front Plant Sci, 2018 Genes encoding thermostable variants of the photosynthesis heat-labile protein Rubisco activase (Rca) from a wild relative Oryza australiensis were overexpressed in domesticated rice (Oryza sativa).
