      abstract     = {Hfq is a bacterial protein involved in RNA metabolism.
                      Besides this, Hfq's role in DNA restructuring has also been
                      suggested. Since this mechanism remains unclear, we examined
                      the DNA conformation upon Hfq binding by combining
                      vibrational spectroscopy and neutron scattering. Our
                      analysis reveals that Hfq, which preferentially interacts
                      with deoxyadenosine rich sequences, induces partial opening
                      of dA–dT sequences accompanied by sugar repuckering of the
                      dA strand and hence results in a heteronomous A/B duplex.
                      Sugar repuckering is probably correlated with a global
                      dehydration of the complex. By taking into account Hfq's
                      preferential binding to A-tracts, which are commonly found
                      in promoters, potential biological implications of Hfq
                      binding to DNA are discussed.},
