Isolated polynucleotide containing a polynucleotide sequence selected from the group a) polynucleotide that is at least 70% identical with a polynucleotide that codes for a polypeptide containing the amino acid sequence of SEQ ID No. 2, b) polynucleotide that codes for a polypeptide containing an amino acid sequence that is at least 70% identical with the amino acid sequence of SEQ ID No. 2, c) polynucleotide that is complementary to the polynucleotide of a) or b), and d) polynucleotide containing at least 15 consecutive nucleotides of the polynucleotide sequence of a), b) or c), and a process for the production of L-amino acids by fermentation using coryneform bacteria in which at least the luxR gene is present in attenuated form, and the use of the polynucleotide sequences as hybridization probes.
