Abstract

The invention relates to isolated nucleotide sequences from Coryneform bacteria which code for the pck gene encoding the enzyme phosphoenol pyruvate carboxykinase (PEP carboxykinase). The invention also relates a process for the fermentative preparation of L-amino acids, in particular L-lysine, L-threonine, and L-glutamate by attenuation of the pck gene.
