16-Hydroxytabersonine is a terpene indole alkaloid produced by the plant Catharanthus roseus. The metabolite is an intermediate in the formation of vindoline, a precursor needed for formation of the pharmaceutically valuable vinblastine and vincristine. 16-hydroxytabersonine is formed from the hydroxylation of tabersonine by tabersonine 16-hydroxylase (T16H). Tabersonine 16-O-methyltransferase (16OMT) methylates the hydroxylated 16 position to form 16-methoxytabersonine.[1]
