Abstract: The mutation of the endA and recA genes in E. coli strain BL21 creates features that are very attractive for protein expression and cloning in a single prokaryotic system, including rapid cell growth, high transformation efficiency, rapid plasmid replication to high densities, and high plasmid stability. When specially prepared for competence, these strains are highly useful for both cloning and protein expression.
