The present invention relates to the use of nucleic acid sequences for regulating the transcription and expression of genes, the novel promoters and expression units themselves, methods for altering or causing the transcription rate and/or expression rate of genes, expression cassettes comprising the expression units, genetically modified microorganisms with altered or caused transcription rate and/or expression rate, and methods for preparing biosynthetic products by cultivating the genetically modified microorganisms.
摘要:
The present invention features methods of increasing the production of a fine chemical, e.g., lysine from a microorganism, e.g., Corynebacterium by way of deregulating an enzyme encoding gene, i.e., fructose-1,6-bisphosphatase. In a preferred embodiment, the invention provides methods of increasing the production of lysine in Corynebacterium glutamicum by way of increasing the expression of fructose-1,6-bisphosphatase activity. The invention also provides a novel process for the production of lysine by way of regulating carbon flux towards oxaloacetate (OAA). In a preferred embodiment, the invention provides methods for the production of lysine by way of utilizing fructose or sucrose as a carbon source.
