Experimental evidence for extra proton exchange in ribulose 1,5-bisphosphate carboxylase/oxygenase catalysis [PDF]
Communicative & Integrative Biology, 2022 Despite considerable advances in the past 50 y, the mechanism of ribulose 1,5-bisphosphate carboxylase/oxygenase (Rubisco) catalysis is still not well understood.

Ribulose 1,5-bisphosphate carboxylase/oxygenase activates O2 by electron transfer. [PDF]
Proc Natl Acad Sci U S A, 2020 Significance Despite its enormous evolutionary success (it is the carboxylating enzyme of all photosynthetic pathways from microorganisms to higher plants), Rubisco is rather inefficient due to wasteful competitive inhibition by molecular oxygen.

Oxidative stress-induced formation of covalently linked ribulose-1,5-bisphosphate carboxylase/oxygenase large subunit dimer in tobacco plants [PDF]
BMC Research Notes, 2019 Objective Many abiotic stresses cause the excessive accumulation of reactive oxygen species known as oxidative stress. While analyzing the effects of oxidative stress on tobacco, we noticed the increased accumulation of a specific protein in extracts ...

An insight: Impact of reduced Rubisco on plant physiology and biochemistry
The Indian Journal of Agricultural Sciences, 2021 Photosynthesis is a process of conversion of sunlight energy and atmospheric carbon to organic molecules with the help of a key and that is Ribulose-1,5-bisphosphate carboxylase/oxygenase. Ribulose-1,5-bisphosphate carboxylase/ oxygenase (RubisCo) is one

Bicarbonate Inhibits Ribulose-1,5-Bisphosphate Carboxylase [PDF]
Plant Physiology, 1988 Ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBPCO) rapidly extracted from leaves of wheat (Triticum aestivum) and purified activated RuBPCO were incubated in the presence and absence of 20 millimolar HCO(3) (-) and changes in activation state were followed.
