Kinetics of structural reorganizations in multilamellar photosynthetic membranes monitored by small angle neutron scattering
We demonstrate the power of time-resolved small-angle neutron scattering experiments for the
investigation of the structure and structural reorganizations of multilamellar photosynthetic membranes.
In addition to briefly summarizing our results on thylakoid membranes isolated from higher plants and
in unicellular organisms, we discuss the advantages and technical and methodological limitations of timeresolved
SANS. We present a detailed and more systematical investigation of the kinetics of light-induced
structural reorganizations in isolated spinach thylakoid membranes, which show how changes in the repeat
distance and in the long-range order of the multilamellar membranes can be followed with a time resolution
of seconds. We also present data from comparative measurements performed on thylakoid membranes
isolated from tobacco
