Description | One member of this family, as characterised in Klebsiella terrigena [ ], is able to interconvert acetoin + NADH with meso-2,3-butanediol + NAD(+). It is also capable of irreversible reduction of diacetyl with NADH to acetoin. There has been a reuctance to classify the enzyme as either , which is (R,R)-butanediol dehydrogenase, or , which is acetoin dehydrogenase without a specified stereochemistry [ ]. Another member of this family, from Corynebacterium glutamicum (Brevibacterium flavum), is called L-2,3-butanediol dehydrogenase [].This enzyme is a homotetramer in the family of short chain dehydrogenases. | Name | Acetoin reductase |
Short Name | 23BDH | Type | Family |
