Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) is the major enzyme assimilating CO (2) into the biosphere. At the same time Rubisco is an extremely inefficient catalyst and its carboxylase activity is compromised by an opposing oxygenase activity involving atmospheric O (2). The shortcomings of Rubisco have implications for crop yield, nitrogen and water usage, and for the global carbon cycle. The N-terminal domain of RuBisCO large chain adopts a ferredoxin-like fold. Literature references. Taylor TC, Andersson I; , J Mol Biol 1997;265:432-444.: The structure of the complex between rubisco and its natural substrate ribulose 1,5-bisphosphate.

The pyrenoid is a proteinaceous structure where most of the Rubisco is located. The pyrenoid undergoes a dramatic morphological change when cells are switched from high- to low-CO 2 conditions (76) (Fig. 3). When the CCM is functional, a starch sheath appears around the pyrenoid and 90% of Rubisco is present in the pyrenoid (11, 52, 70). Apr 04, 2020 · Proteins serve a variety of cellular functions. Many of them are enzymes, some are antibodies, some are receptors, some are hormones and some others are structural proteins. Collagen is the most abundant protein in animal world and Ribulose bisphosphate Carboxylase-Oxygenase (RuBisCO) is the most abundant protein in the whole of the biosphere. Jun 06, 2016 · Ribulose 1,5- bisphosphate carboxylase/oxygenase is an enzyme that catalyzes the attachement of Co2 to ribulose 1,5-bisphosphate and leading to formation of six carbon unstable compound .

- ATP synthase structure and function may be altered by large ionic concentrations (particularly Mg2+) which are associated with cellular dehydration. - It is not the Calvin cycle per se that loses function, but the ATP fuel supply driven by the light reactions that puts a brake on the Calvin cycle.

Rubisco is inherently inefficient because it can also catalyze a reaction with oxygen, giving a wasteful process known as photorespiration (rather than photosynthesis). To overcome this inefficiency, the C 4 pathway initially fixes atmospheric CO 2 into C 4 acids using the enzyme phosphoenolpyruvate carboxylase that is insensitive to O 2 .
