BL21(DE3) ΔserC Chemically Competent E.coli Cells for Protein Phosphorylation

Amid Biosciences’ BL21(λDE3) ΔserC is an engineered strain where serC gene was deleted to reduce the intracellular levels of phosphoserine. The abundance of phosphoserine in E.coli cells interferes with a site-specific incorporation of non-natural analogs of phosphoserine or phosphothreonine into recombinant proteins. In E. coli, phosphoserine is synthesized from 3-phosphohydroxypyruvate by phosphoserine aminotransferase encoded by serC gene.
