Systems Analyses Reveal the Resilience of Escherichia coli

Productivity of bacterial cell factories is frequently compromised by stresses imposed by recombinant protein synthesis and carbon-to-product conversion but little is known about these bioprocesses at a systems level Production of the unnatural metabolite citramalate in Escherichia coli requires the expression of a single gene coding for citramalate synthase
