indicated that AbHDH was able to not only reduce hyoscyamine aldehyde to produce hyoscyamine but also oxidize hyoscyamine to form hyoscyamine aldehyde under different conditions. To elucidate its catalytic mechanism, the crystal structure of AbHDH at a 2.4-Å resolution was also determined. Overexpression of AbHDH significantly enhanced the biosynthesis of hyoscyamine and the production of anisodamine and scopolamine

The incorporation of oxygen-18 from (RS)-phenyl- [2-18O,2-2H]lactate into the tropane alkaloids littorine 1 and hyoscyamine 2 in Datura stramonium reveals that up to 29% of the oxygen-18 is lost during the transformation of 1 to 2.
