Published in 2022 at "Frontiers in Bioengineering and Biotechnology"

DOI: 10.3389/fbioe.2022.830712

Abstract: Several regiospecific enantiomers of hydroxy-(S)-equol (HE) were enzymatically synthesized from daidzein and genistein using consecutive reduction (four daidzein-to-equol–converting reductases) and oxidation (4-hydroxyphenylacetate 3-monooxygenase, HpaBC). Despite the natural occurrence of several HEs, most of them had… read more here.
