In research recently completed at Emory University School of Medicine, scientists have discovered a mutant enzyme that could enable plants to use and convert carbon dioxide more quickly, effectively taking more of that gas out of the atmosphere.

During photosynthesis, plants and some bacteria convert sunlight and carbon dioxide into usable chemical energy. Scientists have long known that this process relies on the enzyme rubulose 1,5-bisphosphate carboxylase/oxygenase, also called RuBisCO. While RuBisCO is the most abundant enzyme in the world, it is also one of the least efficient. As Dr. [Ichiro] Matsumura [assistant professor of biochemistry at Emory University School of Medicine] says, "All life pretty much depends on the function o[f] this enzyme. It actually has had billions of years to improve, but remains about a thousand times slower than most other enzymes. Plants have to make tons of it just to stay alive."RuBisCO's inefficiency limits plant growth and stops organisms from using and assimilating all the carbon dioxide in the atmosphere, even as the amount of gas in the atmosphere continues to grow. The resulting gas buildup is one cause of global warming.
Basically, what they did was engineer a genetic mutation of RuBisCO to make it far more efficient at assimilating carbon dioxide.
