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

Rubisco activase remodels plant Rubisco via the large subunit N-terminus [PDF]
J Biol Chem, 2020 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]
BMC Plant Biology, 2019 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 putative RuBisCo activase (TaRca1) ˗ the catalytic chaperone regulating carbon assimilatory pathway in wheat (Triticum aestivum) under the heat stress [PDF]
Frontiers in Plant Science, 2016 RuBisCo activase (Rca) is a catalytic chaperone involved in modulating the activity of RuBisCo (key enzyme of photosynthetic pathway). Here, we identified eight novel transcripts from wheat through data mining predicted to be Rca and cloned a transcript ...

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 ...

Rubisco's chiropractor: a study of higher plant Rubisco activase
, 2015 Rubisco activase operates as the chaperone responsible for maintaining the catalytic competency of Ribulose 1,5-bisphophate carboxylase oxygenase (Rubisco) in plants. Rubisco is notoriously inefficient, rapidly self-inactivating under physiological conditions. Rubisco activase uses the power released from the hydrolysis of ATP to power a conformational

Antisense RNA inhibition of Rubisco activase expression [PDF]
The Plant Journal, 1994 SummaryRibulose bisphosphate carboxylase (Rubisco) activase catalyzes the activation of Rubisco in vivo. Activase antisense DNA mutants of tobacco have been generated to explore the control that activase exerts on the photosynthetic process. These mutants have up to 90% reductions in activase protein levels as a consequence of an inhibition of activase

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 ...
