Application

Application Comment Organism
synthesis the enzyme is useful, together with menthone:(+)-neomenthol reductase (EC 1.1.1.208), for production of (1R,2S,5R)-(-)-menthol and (1S,2S,5R)-(+)-neomenthol from pulegone, development of a one-pot synthesis method, overview. Menthol isomers, (1R,2S,5R)-(-)-menthol, (1R,2S,5S)-(+)-isomenthol, (1S,2S,5R)-(+)-neomenthol, and (1R,2R,5R)-(+)-neoisomenthol, and carvone are used as additives in oral hygiene products and flavors in food and beverages, or cosmetics Mentha x piperita

Protein Variants Comment Organism
additional information development of a one-pot (bio)synthesis of (1R,2S,5R)-(-)-menthol and (1S,2S,5R)-(+)-neomenthol from pulegone, using recombinant Escherichia coli extracts that contain the biosynthetic genes for an ene-reductase NtDBR from Nicotiana tabacum and two menthone dehydrogenases, MMR and MNMR from Mentha piperita, a modular engineering strategy to improve the final production level. Multigene-construct-derived enzyme mixtures production of menthone, isomenthone, menthol, and neomenthol, but no or poor production of neoisomenthol and isomenthol, overview Mentha x piperita
