Ribulose Bisphosphate Carboxylase [PDF]

open access: yesPlant Physiology, 1977
A decaploid tall fescue (Festuca arundinacea Schreb) genotype has been found which exhibits net photosynthetic rates of 32 to 41 mg CO(2)/dm(2).hour as opposed to a mean of 22 mg CO(2)/dm(2).hour for 10 hexaploid genotypes. The decaploid genotype exhibited a ribulose 1,5-bisphosphate (RuBP) carboxylase specific activity 1.3- to 2-fold higher than ...

Protein-Bound Ribulose Bisphosphate Correlates with Deactivation of Ribulose Bisphosphate Carboxylase in Leaves [PDF]

open access: yesPlant Physiology, 1988
Previous reports indicate that ribulose 1,5-bisphosphate (RuBP) binds very tightly to inactive ribulose bisphosphate carboxylase (rubisco) in vitro. Therefore, we decided to investigate whether there was evidence for tight binding of RuBP associated with deactivation of rubisco in vivo.

Storage and Maintaining Activity of Ribulose Bisphosphate Carboxylase/Oxygenase [PDF]

open access: yesPlant Physiology, 1981
Purified ribulose-1,5-bisphosphate carboxylase/oxygenase in 50% saturated (NH(4))(2)SO(4) was stable when frozen as small beads in liquid nitrogen and stored at -80 C. When stored as a slurry at 4 C most of the activity was lost within four weeks. This loss was due not only to enzyme polymerization.

An ancient metabolite damage-repair system sustains photosynthesis in plants

open access: yesNature Communications, 2023
Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) is the major catalyst in the conversion of carbon dioxide into organic compounds in photosynthetic organisms. However, its activity is impaired by binding of inhibitory sugars such as xylulose-1,5-

Bicarbonate uptake experiment show potential karst carbon sinks transformation into carbon sequestration by terrestrial higher plants

open access: yesJournal of Plant Interactions, 2022
Karstification forms tremendous karst carbon sinks in the Earth. Whether terrestrial higher plants can absorb and utilize bicarbonate, there is a key testimony that karst carbon sinks can be transformed into carbon sequestrations by terrestrial higher ...

Exploring the oxygenase function of Form II Rubisco for production of glycolate from CO2

open access: yesAMB Express, 2021
The oxygenase activity of Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) converts ribulose-1,5-bisphosphate (RuBP) into 2-phosphoglycolate, which in turn channels into photorespiration, resulting in carbon and energy loss in higher plants.

Protocol to analyze the inhibitory effect of free organic carbon generated by chemoautotrophic bacteria on their CO2 fixation

open access: yesSTAR Protocols, 2023
Summary: Here, we present a protocol to analyze the inhibition of self-generated extracellular free organic carbon (EFOC) on CO2 fixation by chemoautotrophic bacteria. We detail the construction and operation of membrane reactor, followed by a simulation

Effect of salicylic acid pretreatment on cadmium toxicity in wheat

open access: yesBiologia Plantarum, 2010
Cadmium (100, 400 and 1000 μM CdCl2) treatments resulted in the inhibition of root dry biomass, root elongation and increased Cd accumulation in wheat (Triticum aestivum L.) roots.

Effects of OsRCA Overexpression on Rubisco Activation State and Photosynthesis in Maize

open access: yesPlants, 2023
Ribulose–1,5–bisphosphate carboxylase/oxygenase (Rubisco) is the rate–limiting enzyme for photosynthesis. Rubisco activase (RCA) can regulate the Rubisco activation state, influencing Rubisco activity and photosynthetic rate. We obtained transgenic maize

Continuous artificial synthesis of glucose precursor using enzyme-immobilized microfluidic reactors

open access: yesNature Communications, 2019
Ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) is a difficult enzyme to work with. Here, the authors covalently immobilized it in a microfluidic reactor to enhance its storage/thermal stabilities and reusability, which enabled the continuous ...
