Summary: Display of proteins on the bacterial cell surface has always been an attractive technique for the production of functional cell-anchored proteins, thereby reducing the cost, time and effort related to enzyme purification. Thus, surface display can enable fast and easy screening of protein libraries, e.g. activity variants, or screening of different enzyme substrates, while maintaining a connection between the phenotype and the genotype. Additionally, cells displaying functional enzymes can potentially be used as whole-cell catalysts.This protocol describes how to express proteins on the surface of E. coli BL21 (DE3) using a L-rhamnose inducible expression system.
