  • Patent number: 6664088
    Abstract: A method of producing vanillin comprising the steps of: (1) providing trans-ferulic acid or a salt thereof; and (2) providing trans-ferulate: CoASH ligase activity (enzyme activity I), trans-feruloyl ScoA hydratase activity (enzyme activity II), and 4-hydroxy-3-methoxyphenyl-&bgr;-hydroxy-propionyl SCoA (HMPHP SCoA) cleavage activity (enzyme activity III). Conveniently the enzymes are provided by Pseudomonas fluorescens Fe3 or a mutant or derivative thereof. Polypeptides with enzymes activities II and III and polynucleotides encoding the polypeptides. Use of the polypeptides or the polynucleotides in a method for producing vanillin is also provided.
    Type: Grant
