title: Structural and thermodynamic characteristics of the binding of the lambda N protein to a RNA hairpin.
abstract: The specific binding of the lambda N protein to a 15 nucleotide RNA oligomer that forms a hairpin structure has been investigated by biophysical methods. Using fluorescence spectroscopy and equilibrium ultra-centrifugation, it was found that the N protein binds specifically to this RNA hairpin as a monomer. Circular dichroism experiments show that both the N protein and the RNA hairpin undergo structural change upon association of the complex.
