Tabersonine is a terpene indole alkaloid found in the medicinal plant Catharanthus roseus. Tabersonine is hydroxylated at the 16 position by the enzyme tabersonine 16-hydroxylase (T16H) to form 16-hydroxytabersonine.^[1] The enzyme leading to its formation is currently unknown. Tabersonine is the first intermediate leading to the formation of vindoline one of the two precursors required for vinblastine biosynthesis.
