| Research Abstract |
Dietary compounds such as polyphenols are conjugated by UGT and SULT isoforms and its biological effects depend, in partly, on formation of the conjugates. In order to investigate the sequential metabolism of the dietary bioflavonoid in vitro, xenobiotic metabolizing enzymes, several human P450 and UGT were coexpressed in Saccharomyces cerevisiae AH22. These human P450 and UGT co-expression system in yeast allows us to investigate the sequential biotransformation of xenobiotics including dietary flavonoids to be simulated in vitro.
