Abstract (en)

[origin: WO9323547A1] The enantioselective hydrolysis of racemic naproxen esters by ester hydrolases using hydrolases derived from a panel of microorganisms is described, the most suitable of which was the microorganism Zopfiella latipes. The ester hydrolases are of use in a low cost, high yield hydrolysis of racemic naproxen esters.
