ABSTRACT:
An isolated polynucleotide which contains a polynucleotide sequence selected from the group comprising:(a) a polynucleotide which is at least 70% identical to a polynucleotide coding for a polypeptide containing the amino acid sequence of SEQ ID No. 2,(b) a polynucleotide coding for a polypeptide containing an amino acid sequence which is at least 70% identical to the amino acid sequence of SEQ ID No. 2,(c) a polynucleotide which is complementary to the polynucleotides of (a) or (b), and(d) a polynucleotide containing at least 15 consecutive nucleotides of the polynucleotide sequence of (a), (b), or (c),and a fermentation process for the preparation of L-amino acids using corynebacteria in which at least the pknD gene is amplified, and to the use, as hybridization probes, of polynucleotides containing the sequences according to the invention.
