reactions performed at high benzaldehyde concentrations and at high hydrostatic pressures show an increase in (R)-2-hydroxypropiophenone ((R)-2-HPP) formation catalyzed by BFD variants F464I, A460I, and A460I/F464I. For BFD mutant A460I/F464I there is an increase in the ee of (R)-2-HPP up to 80%, whereas at atmospheric conditions this variant synthesizes (R)-2-HPP with an ee of only 50%. Alkaline conditions (up to pH 8.5) and high hydrostatic pressures result in an increase of (R)-2-HPP synthesis, especially in the case of variant A460I and F464I

when 3-ethoxy-4-hydroxybenzoylformate is provided at with Pseudomonas putida, it is completely transformed to ethyl vanillic acid after 2 days, but only trace amounts of ethyl vanillin are detected. Similar results are obtained when ethyl vanillin replaces 3-ethoxy-4-hydroxybenzoylformate as substrate, thus aldehyde dehydrogenation activity in Pseudomonas putida is greater than its synthesis activity. The recombinant Escherichia coli strain expressing the enzyme from Pseudomonas putida converts (S)-3-ethoxy-4-hydroxymandelic acid into ethyl vanillin, but does not degrade ethyl vanillin, overview
