Nucleotide sequences coding for the Corynebacterium glutamicum ptsH gene

摘要

Isolated polynucleotide (I) from coryneform bacteria is a sequence at least 70% identical with a sequence that encodes an 89 amino acid (aa) polypeptide (S2) fully defined in the specification, a sequence that encodes a polypeptide at least 70% identical with (S2), its complement or fragment containing at least 15 consecutive nucleotides (nt) of (I). Independent claims are also included form the following: (1) vector (II) containing (I); (2) coryneform bacteria containing (II); and (3) production of L-aa by fermenting an appropriate coryneform in which the gene encoding component H of the phosphotransferase system is amplified, especially over expressed.
