ssDNA recombineering boosts in vivo evolution of nanobodies displayed on bacterial surfaces

Abstract

Yamal Al-ramahi et al. describe an accelerated laboratory evolution method that applies ssDNA recombineering and bacterial surface display to engineer nanobody epitope recognition. As a proof-of-concept, they evolved TD4 recognition to bind the translocated intimin receptor (TirM) of EPEC pathogens, with this method bypassing the need for laborious cloning and mutagenesis procedures.
