Abstract

Die Erfindung bezieht sich auf ein Verfahren zur Gewinnung einer Pyruvat-decarboxylase durch Isolierung aus einem Produzenten-Organismus. Die Pyruvat-decarboxylase ist zur Bildung von (R)-(-)-Phenylacetylcarbinol (I) in » 95 % Enantiomereneinheit mit einem Produktverhältnis von I zu 2-Hydroxypropiophenon von » 95 % befähigt. Außerdem besitzt die Pyruvat-decarboxylase eine spezifische Aktivität bezüglich der Phenylacetylcarbinolbildung von > 1U/mg. Ziel der Erfindung ist, eine Pyruvat-decarboxylase mit verbesserter Synthesekapazität bezüglich der Bildung von (R)-(-)-Phenylacetylcarbinol zu erhalten. Das zu diesem Zweck entwickelte erfindungsgemäße Verfahren zeichnet sich dadurch aus, daß man einen Produzenten-Organismus mit einem für Pyruvat-decarboxylase kodierenden Gen aus Zymomonas mobilis verwendet, in dessen DNA-Sequenz das für den Tryptophanrest kodierende Kodon TGG an der Position 1174-1176 durch ein Kodon ersetzt ist, das für einen Aminosäurerest mit verminderter Raumerfüllung kodiert.
