Nocardia species NRRL 5646 stereospecifically hydrates 4-vinylphenol (15) to S-1-(4'-hydroxyphenyl)ethanol (17), and further oxidizes 17 to 4'-hydroxyacetophenone (18). Labeled metabolites 17 and 18 obtained from incubations in D2O and H218O support initial enzymatic tautomerization of 15 to a reactive quinone methide (16), which adds water in the first reaction. Commitment to catalysis is high in the hydration reaction, while the alcohol dehydrogenation reaction appears to be reversible.
