ID 1.5.3.6 DE (R)-6-hydroxynicotine oxidase. AN 6-hydroxy-D-nicotine oxidase. AN D-6-hydroxynicotine oxidase. CA (R)-6-hydroxynicotine + H2O + O2 = 6-hydroxypseudooxynicotine + H2O2. CC -!- The enzyme, which participates in nicotine degradation, is specific CC for (R) isomer of 6-hydroxynicotine, derived from the uncommon (R)- CC nicotine. CC -!- The bacterium Arthrobacter nicotinovorans, in which this enzyme was CC originally discovered, has a different enzyme that catalyzes a CC similar reaction with the (S)-isomer (cf. EC 1.5.3.5).
