(R,R)-butanediol dehydrogenase activity
Definition
Target type: molecularfunction
Catalysis of the reversible reaction: (R,R)-butane-2,3-diol + NAD+ = (R)-acetoin + NADH + H+. [EC:1.1.1.4]
(R,R)-Butanediol dehydrogenase activity catalyzes the reversible interconversion of (R,R)-butanediol and acetoin. This enzyme is involved in the biosynthesis of butanediol, a key component of the biofuel butanol. The enzyme utilizes NAD+ as a cofactor, and the reaction proceeds via a hydride transfer mechanism. The stereospecificity of the enzyme is important for the efficient production of butanediol, as other isomers of butanediol are not as useful as biofuel precursors. The enzyme is typically found in bacteria, where it plays a role in the metabolism of carbohydrates and other organic compounds. It has also been found in some fungi and plants. The activity of (R,R)-butanediol dehydrogenase can be influenced by factors such as pH, temperature, and substrate concentration. This enzyme is of great interest to the biofuel industry, as it is a potential target for the development of new and improved biocatalysts for the production of butanol.'
