Fragmento de DNA vetor bactéria corineforme e processo para produzir L-aminoácido ou um ácido nucleico

摘要

The present invention provides a DNA fragment derived from Coryneform bacteria and containing a gene coding for a protein having sucrase activity and a recombinant DNA containing said DNA fragment and capable of gene amplification in Coryneform bacteria. The recombinant DNA is introduced into Coryneform bacteria to enhance their sucrase activity. By using the bacteria having enhanced sucrase activity a method is provided for efficiently producing L-amino acids and nucleic acids in a short period of time.
