Cover Story: DNA metabolism involves the critical processes of replication, recombination, transposition, and repair. While previously believed to occur exclusively in the cytoplasm, this classical view has been challenged by mounting evidence that bacterial DNA transactions are closely associated with the cell membrane. Factors influencing these processes include the Hfq protein, an RNA chaperone, increasingly recognized for important roles in DNA-related functions. This narrative review examines the emerging involvement of membranes in bacterial DNA transactions and the potential regulatory functions of Hfq, highlighting its dual affinity for DNA and membranes.
