We have studied the protein dynamics of three subcore reaction-center complexes of photosystem II: the isolated reaction center (RC), the core antenna CP47, and the CP47 RC complex by means of time-resolved hole-burning in the red wing of their Q y-absorption bands. The dependence of the “effective” homogeneous line width Γ′hom on temperatureT between 1.2 and 4.2 K suggests that optical dephasing in these proteins is determined by two-level systems (TLSs), as in doped organic glasses.
