    Description: The kinetics of Littorine biosynthesis were in agreement with the role of this compound as a direct precursor of hyoscyamine biosynthesis.
    Targets: P450 (e.g. CYP17)
    In vitro:
    Chem Biol. 2006 May;13(5):513-20.
    Functional genomic analysis of alkaloid biosynthesis in Hyoscyamus niger reveals a cytochrome P450 involved in littorine rearrangement.[Pubmed: 16720272]
    Tropane alkaloids are valuable pharmaceutical drugs derived from solanaceous plants such as Hyoscyamus niger (black henbane). The biosynthesis of these molecules, including the nature of the enigmatic rearrangement of (R)-littorine to (S)-hyoscyamine, is not completely understood.
    METHODS AND RESULTS:
    To test the hypothesis that a cytochrome P450 enzyme is involved in this rearrangement, we used virus-induced gene silencing to silence a cytochrome P450, CYP80F1, identified from H. niger roots by EST sequencing. Silencing CYP80F1 resulted in reduced hyoscyamine levels and the accumulation of littorine. Hyoscyamine was observed in CYP80F1-expressing tobacco hairy roots supplied with (R)-littorine. Expression in yeast confirmed that CYP80F1 catalyzes the oxidation of (R)-littorine with rearrangement to form hyoscyamine aldehyde, a putative precursor to hyoscyamine, and without rearrangement to form 3'-hydroxylittorine.
    CONCLUSIONS:
    Our data strongly support the involvement of CYP80F1 in the rearrangement of littorine to hyoscyamine.
