Strategies to Enhance Periplasmic Recombinant Protein Production Yields in Escherichia coli

Frontiers in Bioengineering and Biotechnology, 2021
Main reasons to produce recombinant proteins in the periplasm of E. coli rather than in its cytoplasm are to -i- enable disulfide bond formation, -ii- facilitate protein isolation, -iii- control the nature of the N-terminus of the mature protein, and -iv-
