Limonene-1,2-diol dehydrogenase

Limonene-1,2-diol dehydrogenase (EC 1.1.1.297, NAD⁺-dependent limonene-1,2-diol dehydrogenase) is an enzyme with systematic name menth-8-ene-1,2-diol:NAD⁺ oxidoreductase.^[1] This enzyme catalyses the following chemical reaction

menth-8-ene-1,2-diol + NAD⁺ ${\displaystyle \rightleftharpoons }$ 1-hydroxymenth-8-en-2-one + NADH + H⁺ (general reaction)

(1) (1S,2S,4R)-menth-8-ene-1,2-diol + NAD⁺ ${\displaystyle \rightleftharpoons }$ (1S,4R)-1-hydroxymenth-8-en-2-one + NADH + H⁺

(2) (1R,2R,4S)-menth-8-ene-1,2-diol + NAD⁺ ${\displaystyle \rightleftharpoons }$ (1R,4S)-1-hydroxymenth-8-en-2-one + NADH + H⁺

While the enzyme from the Gram-positive bacterium Rhodococcus erythropolis DCL14 can use both (1S,2S,4R)- and (1R,2R,4S)-menth-8-ene-1,2-diol as substrate, activity is higher with (1S,2S,4R)-menth-8-ene-1,2-diol as substrate.
