Engineering specific mutations in the cAMP receptor protein (CRP) to reprogram global transcriptional regulation. This optimizes metabolic flux toward L-amino acid biosynthesis in Escherichia strains.
The cluster addresses the metabolic limitations and feedback inhibition that restrict the overproduction of L-arginine and L-ornithine in industrial microorganisms. Overcoming these regulatory bottlenecks allows for higher volumetric productivity in fermentation processes.
