 (R,R)-butanediol dehydrogenase

In enzymology, a (R,R)-butanediol dehydrogenase () is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are (R,R)-butane-2,3-diol and NAD, whereas its 3 products are (R)-acetoin, NADH, and H.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD or NADP as acceptor.The systematic name of this enzyme class is (R,R)-butane-2,3-diol
