Metabolism of genistein (open columns) and apigenin (solid columns) using
rat UGT isoforms expressed in yeast strain AH22. From left to right, UGT1A1,
UGT1A3, UGT1A5, UGT1A6, UGT1A7, UGT2B1, UGT2B3, and UGT2B12 were tested with
optimal incubation with either 50 μM genistein or apigenin (number of
replicates, n = 3).
