Abstract: Disclosed herein are methods of bioproduction of enantiomerically pure or enantiomerically enriched 2-phenylglycinol or a derivative thereof by multiple enzyme-catalyzed chemical transformations in a one-pot reaction system.

Abstract: This invention relates to the bioproduction of substituted or unsubstituted phenylacetaldehyde, 2-phenylethanol, phenylacetic acid or phenylethylamine by subjecting a starting material comprising glucose, L-phenylalanine, substituted L-phenylalanine, styrene or substituted styrene to a plurality of enzyme catalyzed chemical transformations in a one-pot reaction system, using recombinant microbial cells overexpressing the enzymes. To produce phenylacetaldehyde from styrene, the cells are modified to overexpress styrene monooxygenase (SMO) and styrene oxide isomerase (SOI). To produce phenylacetic acid from styrene, SMO, SOI and aldehyde dehydrogenase are overexpressed. Alternatively, to produce 2-phenylethanol, SMO, SOI and aldehyde reductase or alcohol dehydrogenase are overexpressed, while to produce phenylethylamine, SMO, SOI and transaminase are overexpressed.
