NUCLEOTIDE SEQUENCES WHICH CODE FOR THE SAHH GENE

摘要

The invention relates to an isolated polynucleotide comprising a polynucleotide sequence chosen from the group consisting of a) polynucleotide which is identical to the extent of at least 70 % to a polynucleotide which codes for a polypeptide which comprises the amino acid sequence of SEQ ID No. 2; b) polynucleotide which codes for a polypeptide which comprises an amino acid sequence which is identical to the extent of at least 70 % to the amino acid sequence of SEQ ID No. 2; c) polynucleotide which is complementary to the polynucleotides of a) or b); and d) polynucleotide comprising at least 15 successive nucleotides of the polynucleotide sequence of a), b) or c); and a process for the fermentative preparation of L-amino acids using coryneform bacteria, in which at least the sahH gene is present in enhanced form, and the use of polynucleotides which contain the sequences according to the invention as hybridization probes.
