Inhibition of ribulose bisphosphate carboxylase by substrate ribulose 1,5-bisphosphate.
Journal of Biological Chemistry, 1983 Substrate ribulose bisphosphate is a potent and a weak inhibitor of the rate of CO2/Mg2+ activation in the carboxylase purified from spinach leaves and Rhodospirillum rubrum, respectively. At 2 degrees C, the concentration of ribulose bisphosphate required for 50% inhibition of the initial rate of CO2/Mg2+ activation was less than 0.4 microM for the ...

Conserved spatial patterning of gene expression in independent lineages of C4 plants
New Phytologist, Volume 249, Issue 1, Page 24-38, January 2026.Summary C4 photosynthesis enhances carbon fixation efficiency by reducing photorespiration through the use of an oxygen‐insensitive carboxylase and spatial separation of photosynthesis between mesophyll and bundle sheath cells. The C4 pathway has evolved independently in > 60 plant lineages, but molecular mechanisms underpinning this convergence remain

Influence of Inorganic Phosphate on Photosynthesis of Wheat Chloroplasts: II. RIBULOSE BISPHOSPHATE CARBOXYLASE ACTIVITY [PDF]
, 2017 Isolated wheat chloroplasts were pre-incubated in the dark in the presence of various concentrations of inorganic phosphate with or without carbon dioxide, oxaloacetate, glycerate, and 3-phosphoglycerate.

Purification and Characterization of a Chloroplast Outer-Envelope-Bound, ATP-Dependent Protein Kinase [PDF]
, 1988 An ATP-dependent protein kinase was partially purified from isolated outer envelope membranes of pea (Pisum sativum L., Progress No. 9) chloroplasts. The purified kinase had a molecular weight of 70 kilodaltons, as determined by sodium dodecyl sulfate ...

New Phytologist, Volume 249, Issue 1, Page 359-372, January 2026.Summary Pyrenoids are algal CO2‐fixing organelles that mediate approximately one‐third of global carbon fixation. Most pyrenoids are traversed by membranes that are thought to supply them with concentrated CO2. Despite the critical nature of these membranes for pyrenoid function, they are poorly understood, with few protein components known in any ...

Plant Production Science, 2013 Five ribulose-1,5-bisphosphate carboxylase/oxygenase small subunit genes identified in the rice (Oryza sativa) genome are designated as OsRBCS1, 2, 3, 4 and 5. OsRBCS1 transcripts were not detectable.

Does Long-Term Elevation of CO2 Concentration Increase Photosynthesis in Forest Floor Vegetation? (Indiana Strawberry in a Maryland Forest). [PDF]
, 1997 As the partial pressure of CO2 (pCO2) in the atmosphere rises, photorespiratory loss of carbon in C3 photosynthesis will diminish and the net efficiency of light-limited photosynthetic carbon uptake should rise.

New Phytologist, Volume 249, Issue 2, Page 675-690, January 2026.Summary Photorespiration is a major source of photosynthetic inefficiency in C3 crops. In photorespiration, the oxygenation rather than carboxylation of RuBP by Rubisco triggers an energy‐expensive pathway to recycle inhibitory byproducts and recapture lost carbon, ultimately reducing yields.

Phosphorylation of chloroplast ribulose bisphosphate carboxylase/oxygenase small subunit by an envelope-bound protein kinase in situ [PDF]
, 1983 A new protein kinase of the cAMP independent type was found to be bound to the outer envelope membrane of spinach chloroplasts. While stimulated by Mg2+ and inhibited by ADP, the enzyme showed no response to conventional protein substrates and was ...
