L-histidine efflux transporter engineering: CJ CheilJedangRecent Research Landscape

The technical lever is the manipulation of specific export proteins to overcome intracellular feedback inhibition. Engineering these efflux mechanisms increases metabolic flux and product yield in microbial production strains.

What technical problems is CJ CheilJedang addressing in L-histidine efflux transporter engineering?

Intracellular amino acid toxicity

(6)evidences

High concentrations of synthesized L-histidine accumulate within the cytoplasm, leading to metabolic feedback inhibition and cellular toxicity. Enhancing export mechanisms prevents growth retardation and increases overall production yield.
