Escherichia coli—the powerhouse for recombinant protein production—is rapidly gaining status as a reliable and efficient host for secretory expression. An improved understanding of protein translocation processes and its mechanisms has inspired and accelerated the development of new tools and applications in this field and, in particular, a more efficient secretion signal. Several important characteristics and requirements are summarised for the design of a more efficient signal peptide for the production of recombinant proteins in E. coli. General approaches and strategies to optimise the signal peptide, including the selection and modification of the signal peptide components, are included. Several challenges in the secretory production of recombinant proteins are discussed, and research approaches designed to meet these challenges are proposed.
