(R)-6-hydroxynicotine oxidase

UniProtKB accession:  P08159

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Involved in the degradation of D-nicotine (PubMed:5849820, PubMed:4628374). Catalyzes the oxidation of (R)-6-hydroxynicotine (6-hydroxy-D-nicotine) to 6-hydroxypseudooxynicotine (PubMed:5849820, PubMed:4965794, PubMed:4628374, PubMed:2680607, PubMed:31046245). Oxidation of the pyrrolidine ring of (R)-6-hydroxynicotine leads to the formation of the optically inactive 6-hydroxy-N-methylmyosmine, which hydrolyzes spontaneously to 6-hydroxypseudooxynicotine (PubMed:4965794, PubMed:4628374, PubMed:31046245). Acts with absolute stereospecificity on the D-form of 6-hydroxynicotine (PubMed:4965794, PubMed:4628374). Shows lower activity with (R)-6-hydroxynornicotine, and weak activity with (R)-4-(1-methylpyrrolidine-2-yl)phenol, (R)-6-chloronicotine and (R)-nicotine (PubMed:31046245).
