| 摘要 |
The invention relates to novel polynucleotides, coding for a polypeptide with citrate synthase activity, bacteria comprising the same, preferably of the species Corynebacterium and Escherichia, and methods for producing amino acids using said bacteria. The invention particularly relates to an isolated polynucleotide, coding for a polypeptide with the amino acid sequence SEQ ID NO:2, wherein the L-aspartic acid in position 5 of the amino acid sequence is replaced by another proteinogenic amino acid and the polypeptide has citrate synthase activity. |
