The invention relates to a method for producing flavone glycoside dihydrochalcones, having the following steps: (a) providing a transgenic microorganism containing (i) a first nucleic acid portion (A) containing a gene which codes for a bacterial chalcone isomerase and (ii) a second nucleic acid portion (B) containing a gene which codes for a bacterial enoate reductase, (b) adding one or more flavone glycosides to the transgenic microorganism under conditions which allow the simultaneous isomerization and reduction of the flavone glycoside into the flavone glycoside dihydrochalcone, and optionally (d) isolating and purifying the final product, wherein the nucleic acid portion (A) (1) is a nucleotide sequence according to SEQ ID NO:1, in which the nucleic acid portion (A') according to SEQ ID NO:3 has been cut out, or (2) is an amino acid sequence according to SEQ ID NO:2, in which the amino acid portion (A&#x2032;) according to SEQ ID NO:4 has been cut out.

The invention provides hydrolases, polynucleotides encoding them, and methods of making and using these polynucleotides and polypeptides. In one aspect, the invention is directed to polypeptides, e.g., enzymes, having a hydrolase activity, e.g., an esterase, acylase, lipase, phospholipase (e.g., phospholipase A, B, C and D activity, patatin activity, lipid acyl hydrolase (LAH) activity) or protease activity, including thermostable and thermotolerant hydrolase activity, and polynucleotides encoding these enzymes, and making and using these polynucleotides and polypeptides. The hydrolase activities of the polypeptides and peptides of the invention include esterase activity, lipase activity (hydrolysis of lipids), acidolysis reactions (to replace an esterified fatty acid with a free fatty acid), transesterification reactions (exchange of fatty acids between triglycerides), ester synthesis, ester interchange reactions, phospholipase activity and protease activity (hydrolysis of peptide bonds). The polypeptides of the invention can be used in a variety of pharmaceutical, agricultural and industrial contexts, including the manufacture of cosmetics and nutraceuticals. In another aspect, the polypeptides of the invention are used to synthesize enantiomerically pure chiral products.
