ATP5F1A and infection: Therefore, we additionally presented a biological feature-based characterization of these phages, and the results revealed particular traits in which these phages differ from reference phages like λ, such as distinct genome integration sites or the use of an additional nut site for antitermination, but also revealed diversity within the group, as observed in the use of different OMR proteins or lipoproteins for infection and superinfection exclusion, respectively.
