abstract：:Puerarin (daidzein 8-C-glucoside) is an isoflavone C-glucoside contained in the roots of Pueraria lobata OHWI. We have previously isolated the human intestinal bacterium, strain PUE, which metabolizes puerarin to daidzein, though the enzyme which cleaves C-glycosidic bond has not been clarified. Here, we identified on...
