pubpic2004jimenez3PEPS and steady-state spectroscopy in combination with binding and structural data, are used to examine the immunological evolution of protein flexibility in an anti-fluorescein antibody. We show that antibody dynamics are systematically manipulated during affinity maturation, and suggest that the evolution of protein flexibility may be a central component of the immune response.
