indole C6 position is challenging. Yet, certain indole prenyltransferases (IPTs) catalyze this reaction efficiently, regiospecifically and under physiological conditions. Through enzyme engineering, in vitro enzymatic reactions and NMR experiments, guided by protein structure analyses, the mechanism was verified by which C6 IPTs catalyze their reactions.
