Transgenic recombinant coli lineage microorganism for L-methionine production

摘要

Transgenic microorganism of recombinant Escherichia coli strain for production of l-methionine, belonging to the modified cell sector by introduction of exogenous genetic material, refers to the Escherichia coli strain K12 mg1655 with targeted chromosomal mutations, in which genes that are related are deleted. methionine transport into the bacterium, meti and metq, as well as the gene regulating methionine production gene, metj, and a plasmid containing gene of interest for methionine production, meta, under the control of synthetic promoter j23100 and region 5? untranslated improved.
