Rubisco: The Enzyme that Keeps on Giving
نویسنده
چکیده
In cyanobacteria, the RbcX protein enhances the production of Rubisco, the multisubunit enzyme that catalyzes the first step of carbon dioxide fixation in most autotrophic organisms. In this issue of Cell, Saschenbrecker et al. (2007) report that RbcX acts as a specific assembly chaperone that mobilizes the large subunits of Rubisco to a specific oligomeric core that can then combine with the small subunits of Rubisco to form the functional holoenzyme.

Activation of Rubisco regulates photosynthesis at high temperature and CO2.
T enzyme Rubisco, short for ribulose1,5-bisphosphate carboxylaseyoxygenase, is the enzyme that incorporates CO2 into plants during photosynthesis. As it constitutes about 30% of the total protein in a plant leaf, Rubisco is probably the most abundant protein on earth and a major sink for plant nitrogen. Rubisco is widely accepted as the ultimate rate-limiting step in photosynthetic carbon fixat...
متن کاملRibulose-1,5-bisphosphate carboxylase/oxygenase activase protein prevents the in vitro decline in activity of ribulose-1,5-bisphosphate carboxylase/oxygenase.
The rate of CO(2) fixation by ribulose-1,5-bisphosphate carboxylase/oxygenase (rubisco) following addition of ribulose 1,5-bisphosphate (RuBP) to fully activated enzyme, declined with first-order kinetics, resulting in 50% loss of rubisco activity after 10 to 12 minutes. This in vitro decline in rubisco activity, termed fall-over, was prevented if purified rubisco activase protein and ATP were ...
متن کاملUnusual ribulose 1,5-bisphosphate carboxylase/oxygenase of anoxic Archaea.
The predominant pool of organic matter on earth is derived from the biological reduction and assimilation of carbon dioxide gas, catalyzed primarily by the enzyme ribulose 1,5-bisphosphate carboxylase/oxygenase (RubisCO). By virtue of its capacity to use molecular oxygen as an alternative and competing gaseous substrate, the catalytic efficiency of RubisCO and the enzyme's ability to assimilate...
متن کاملDifferential Expression of Rubisco in Sporophytes and Gametophytes of Some Marine Macroalgae
Rubisco (ribulose-1, 5-bisphosphate carboxylase/oxygenase), a key enzyme of photosynthetic CO(2) fixation, is one of the most abundant proteins in both higher plants and algae. In this study, the differential expression of Rubisco in sporophytes and gametophytes of four seaweed species--Porphyra yezoensis, P. haitanensis, Bangia fuscopurpurea (Rhodophyte) and Laminaria japonica (Phaeophyceae)--...

BACKGROUND With increasing concerns over global warming and depletion of fossil-fuel reserves, it is attractive to develop innovative strategies to assimilate CO2, a greenhouse gas, into usable organic carbon. Cell-free systems can be designed to operate as catalytic platforms with enzymes that offer exceptional selectivity and efficiency, without the need to support ancillary reactions of meta...
