[https://www.uniprot.org/uniprot/HLNO_PAENI HLNO_PAENI] Involved in the degradation of L-nicotine (PubMed:5849820). Catalyzes the oxidation of (S)-6-hydroxynicotine (6-hydroxy-L-nicotine) to 6-hydroxypseudooxynicotine (PubMed:5849820, PubMed:4965794, PubMed:5646150, PubMed:21383134, PubMed:26744768, PubMed:28080034). Oxidation of the pyrrolidine ring of (S)-6-hydroxynicotine leads to the formation of the optically inactive 6-hydroxy-N-methylmyosmine, which hydrolyzes spontaneously to 6-hydroxypseudooxynicotine (PubMed:4965794, PubMed:21383134, PubMed:26744768, PubMed:28080034). Acts with absolute stereospecificity on the L-form of 6-hydroxynicotine (PubMed:4965794). Can also use (S)-6-hydroxynornicotine (PubMed:26744768, PubMed:28080034).<ref>PMID:21383134</ref> <ref>PMID:26744768</ref> <ref>PMID:28080034</ref> <ref>PMID:4965794</ref> <ref>PMID:5646150</ref> <ref>PMID:5849820</ref>
