titleOfInvention |
Process for obtaining acyloins, pyruvate decarboxylases suitable therefor and their production and dna sequences of the pdc gene coding them |
abstract |
The invention relates to a process for obtaining a pyruvate decarboxylase by isolation from a producer organism. The pyruvate decarboxylase is capable of forming (R)-(-)-phenylacetylcarbinole (I) in >/= 95 % enantiomer unit with a product ratio of (I) to 2-hydroxypropiophenone of >/= 95 %. In addition, the pyruvate decarboxylase has a specific activity with regard to phenylacetylcarbinole formation of > 1 U/mg. It is the aim of the invention to obtain a pyruvate decarboxylase with improved synthesis capacity concerning the formation of (R)-(-)-phenylacetylcarbinole. The process of the invention developed for this purpose is characterized in that use is made of a producing organism with a gene coding for pyruvate decarboxylase from Zymomonas mobilis, in the DNA sequence of which the tryptophane radical coding codon TGG is replaced at position 1174-1176 by a codon which codes for an amino acid radical with a reduced volume ratio. |
