We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

| + | [https://www.uniprot.org/uniprot/HLNO_SHIS7 HLNO_SHIS7] Involved in the degradation of L-nicotine (PubMed:25002425). Catalyzes the oxidation of (S)-6-hydroxynicotine (6-hydroxy-L-nicotine) to 6-hydroxypseudooxynicotine (PubMed:25002425). 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:25002425). Acts with absolute stereospecificity on the L-form of 6-hydroxynicotine (PubMed:25002425). Also involved in the degradation of nornicotine, and catalyzes the oxidation of 6-hydroxynornicotine to 6-hydroxymyosmine, which hydrolyzes to 6-hydroxypseudooxynornicotine (PubMed:27568381). In vitro, converts (S)-nicotine into N-methylmyosmine, which spontaneously hydrolyzes spontaneously into pseudooxynicotine, but catalytic efficiency is about 1900-fold higher with (S)-6-hydroxynicotine (PubMed:25002425).<ref>PMID:25002425</ref> <ref>PMID:27568381</ref> | ||
