Comments

FUNCTION: Catalyzes the regio- and stereoselective reversible NAD-dependent reduction of (6R)-2,2,6-trimethyl-1,4-cyclohexanedione (levodione) to (4R,6R)-4-hydroxy-2,2,6-trimethylcyclohexanone (actinol).
CATALYTIC ACTIVITY: (4R,6R)-4-hydroxy-2,2,6-trimethylcyclohexanone + NAD⁺ = (6R)-2,2,6-trimethyl-1,4-cyclohexanedione + NADH.
ENZYME REGULATION: Strongly activated by monovalent cations, such as K(+), Na(+), and NH4(+).
SIMILARITY: Belongs to the short-chain dehydrogenases/reductases (SDR) family.
