We report a stepwise FLAG-tagging strategy for the purification of target proteins for bioactive metabolites. This method realizes the microscale purification and identification of target protein from as few as 1 × 105 differentiated cells. Using this method, we isolated and identified MetE as a cytosolic target protein of potassium isolespedezate, a metabolite controlling plant nyctinasty.
