- le gène xy/E codant pour la synthèse de la catéchol 2,3-oxygénase, et - un promoteur de l'expression fonctionnelle du gène xy/E dans une bactérie gram . The present invention relates to a vector plasmid characterized in that it comprises at least: - the xy / E gene coding for the synthesis of catechol 2,3-oxygenase, and - a promoter of the functional expression of the xy / E gene in a gram bacterium. n n n The bacteria transformed using these plasmids can be used for DNA cloning and also for the synthesis of catechol 2,3-oxygenase. |
