Systems and Synthetic Metabolic Engineering for Amino Acid Production - the Heartbeat of Industrial Strain Development

With a world market of more than four million tons per year, l-amino acids are among the most important products in industrial biotechnology. The recent years have seen a tremendous progress in the development of tailor-made strains for such products, intensively driven from systems metabolic engineering, which upgrades strain engineering into a concept of optimization on a global scale. This concept seems especially valuable for efficient amino acid production, demanding for a global modification of pathway fluxes - a challenge with regard to the high complexity of the underlying metabolism, superimposed by various layers of metabolic and transcriptional control.
