Persistent non-photochemical hole burning at 4.2 K is an efficient experimental tool to unravel position and nature of low-energy excitonic states in pigment-protein complexes. This is demonstrated here for the case of the trimeric chlorophyll (Chl)

Dynamics-function correlations are usually inferred when molecular mobility and protein function are simultaneously impaired at characteristic temperatures or hydration levels. In this sense, excitation energy transfer in the photosynthetic light-har

Vibrational dynamics of the light-harvesting complex II (LHC II) from spinach was investigated by quasi- and inelastic neutron scattering (QENS and INS) at three different temperatures of 80, 160, and 285 K. QENS/INS spectra of solubilised LHC II and

Photosystem II from thylakoid membranes of the thermophilic cyanobacterium Thermosynechococcus elongatus was solubilized with n-beta-dodecylmaltoside and purified using anion exchange chromatography. Molecular weight, pigment stoichiometry and subuni

In the crystal structure of photosystem II (PSII) from the cyanobacterium Thermosynechococcus elongatus at 3.2 A resolution, several loop regions of the principal protein subunits are now defined that were not interpretable previously at 3.8 A resolu

Stepwise two-photon excitation of chlorophyll a and b in the higher plant main light-harvesting complex (LHC II) and the minor complex CP29 (as well as in organic solution) with 100-fs pulses in the Q(y) region results in a weak blue fluorescence. Th
