Resumen:
Hyoscyamine and scopolamine are tropane alkaloids widely used as pharmaceuticals due to their anticholinergic activity. Scopolamine is the more valuable, with a demand 10 times higher than that of hyoscyamine [1, 2] . Brugmansia candida (syn Datura candida) is a South American native plant and a tropane alkaloid producer [3]. The conversion of hyoscyamine into scopolamine and 6b-hydroxyhyoxcyamine (anisodamine) is carried out by Hyoscyamine 6-b hydroxylase (H6H, EC 1.14.11.11). The development of a recombinant cell harbouring the plant enzyme constitutes an interesting and useful strategy for performing pharmaceutical processes This work reports the functional expression of H6H enzyme in Saccharomyces cerevisiae as a potential tool for the industrial production of scopolamine
