PRODUCTION OF VANILLIN

摘要

A method of producing vanillin comprising the steps of: (1) providing transferulic 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-.beta.-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 said polypeptides. Use of said polypeptides or said polynucleotides in a method for producing vanillin.
