Bacteriophage λ (lambda) infects Escherichia coli and induces a dramatically increased rate and altered profile of genetic recombination as part of the cycle of infection. The genetic recombination processes augment the host-encoded recombina-tion proteins with phage-encoded recombination proteins, promoting particular recombination pathways. This review char-acterizes the protein machinery involved in the most important processes underlying λ-mediated genetic recombination
