Desacetoxyvindoline is a product formed by the methylation of the nitrogen on the indole ring by the enzyme 3-hydroxy-16-methoxy-2,3-dihydrotabersonine N-methyltransferase (NMT).[1] The metabolite is a substrate for desacetoxyvindoline 4-hydroxylase (D4H) which catalyzes a hydroxylation to yield deacetylvindoline.[2] References1. ^Liscombe, Usera and O’connor (2010) Homolog of tocopherol C methyltransferases catalyzes N methylation in anticancer alkaloid biosynthesis.
