Accepted name: dihydrocarveol dehydrogenase
Reaction: menth-8-en-2-ol + NAD+ = menth-8-en-2-one + NADH + H+
Glossary: (+)-dihydrocarveol = (1S,2S,4S)-menth-8-en-2-ol
(+)-isodihydrocarveol = (1S,2S,4R)-menth-8-en-2-ol
(+)-neoisodihydrocarveol = (1S,2R,4R)-menth-8-en-2-ol
(–)-dihydrocarvone = (1S,4S)-menth-8-en-2-one
(+)-isodihydrocarvone = (1S,4R)-menth-8-en-2-one
Other name(s): carveol dehydrogenase (ambiguous)
Systematic name: menth-8-en-2-ol:NAD+ oxidoreductase
Comments: This enzyme from the Gram-positive bacterium Rhodococcus erythropolis DCL14 forms part of the carveol and dihydrocarveol degradation pathway. The enzyme accepts all eight stereoisomers of menth-8-en-2-ol as substrate, although some isomers are converted faster than others. The preferred substrates are (+)-neoisodihydrocarveol, (+)-isodihydrocarveol, (+)-dihydrocarveol and (–)-isodihydrocarveol.
