Experimental and DFT 1H NMR study of conformational equilibria in trans-4′,7-dihydroxyisoflavan-4-ol and trans-isoflavan-4-ol

The solution-state conformational equilibria of trans-4′ ,7-dihydroxyisoflavan-4-ol (1) and transisoflavan-4-ol (2) were assessed based on the temperature dependence of their vicinal coupling constants J H-2α,H-3 and JH-3,H-4 in comp

ENZYME ASSOCIATED WITH EQUOL SYNTHESIS

An object of the present invention is to provide enzymes associated with equol synthesis, genes coding such enzymes, and a process for producing equol and its intermediates using the enzymes and genes. The present invention provides a dihydrodaidzein synthesizing enzyme, tetrahydrodaidzein synthesizing enzyme, equol synthesizing enzyme, and genes coding these enzymes. The present invention also provides a process for synthesizing dihydrodaidzein, tetrahydrodaidzein, and/or equol using these enzymes.
