IntEnz Enzyme Nomenclature
EC 1.5.3.6

Names

Accepted name:
(R)-6-hydroxynicotine oxidase
Other names:
6-hydroxy-D-nicotine oxidase
D-6-hydroxynicotine oxidase
Systematic name:
(R)-6-hydroxynicotine:oxygen oxidoreductase

Reactions

Cofactor

Comments:

A flavoprotein (FAD). The enzyme, which participates in nicotine degradation, is specific for (R) isomer of 6-hydroxynicotine, derived from the uncommon (R)-nicotine. The bacterium Arthrobacter nicotinovorans, in which this enzyme was originally discovered, has a different enzyme that catalyses a similar reaction with the (S)-isomer (cf. EC 1.5.3.5, (S)-6-hydroxynicotine oxidase).
