The world's population may reach 10 billion by 2050, but 10% still suffer from food shortages. At the same time, global warming threatens food security by decreasing crop yields, so it is necessary to develop crops with enhanced resistance to high ...

Global warming threatens food security by decreasing crop yields through damage to photosynthetic systems, especially Rubisco activation. We examined whether co-overexpression of Rubisco and Rubisco activase improves the photosynthetic and growth ...

Abstract Rubisco is possibly the most important enzyme on Earth, certainly in terms of amount. This review describes the initial reports of ribulose 1,5-bisphosphate carboxylating activity. Discoveries of core concepts are described, including its quaternary structure, the requirement for post-translational modification, and its role as ...

Improving photosynthesis through the enhancement of Rubisco carboxylation capacity.
Biochemical Society Transactions, 2021Rising human population, along with the reduction in arable land and the impacts of global change, sets out the need for continuously improving agricultural resource use efficiency and crop yield (CY).

Heat sensitivity of Rubisco, Rubisco activase and Rubisco binding protein in higher plants
Acta Physiologiae Plantarum, 2004During the past few years the investigations concerning Rubisco and the changes of its activity and properties at elevated temperature were reconsidered with special reference to the important role of Rubisco activase and Rubisco binding protein. The major changes in Rubisco, Rubisco activase and Rubisco binding protein reported recently are presented ...

Trends in Plant Science, 2018
Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) fixes atmospheric CO2 into organic compounds and is composed of eight copies each of a large subunit (RbcL) and a small subunit (RbcS). Recent reports have revealed unusual RbcS, which are expressed in particular tissues and confer higher catalytic rate, lesser affinity for CO2, and a more ...

The regulation of Rubisco by Rubisco activase
Journal of Experimental Botany, 1995Abstract The activity of Rubisco depends on the conversion of the inactive form (E) to the active form (ECM); the binding of the inhibitors CA1P and RuBP to ECM and E, respectively; and the catalytic formation of inhibitory sugar bisphosphates from the enediol intermediate that precedes carboxylation/oxygenation.

The activity of Rubisco’s molecular chaperone, Rubisco activase, in leaf extracts
Photosynthesis Research, 2011Rubisco frequently undergoes unproductive interactions with its sugar-phosphate substrate that stabilize active sites in an inactive conformation. Restoring catalytic competence to these sites requires the "molecular chiropractic" activity of Rubisco activase (activase).

Publisher Summary This chapter discusses the carbon concentrating mechanism and how Rubisco may access its substrates under different growth conditions, particularly limiting CO2. Rubsico is capable of competing oxygenation reaction, which generates one molecule of 3-PGA and one of 2-phosphoglycolate from RuBP.

Nature, 2006 Rubisco is said to be both the most important enzyme on Earth and surprisingly inefficient. Yet an understanding of the reaction by which it fixes CO2 suggests that evolution has made the best of a bad job.
