The chlorophylls are a structurally and functionally distinct group of macrocyclic tetrapyrrole
pigments that may occur at the porphyrin, chlorin or bacteriochlorin oxidation levels …

▪ Abstract Recent progress in two-dimensional and three-dimensional electron and X-ray
crystallography of Photosystem II (PSII) core complexes has led to major advances in the …

Tetrapyrrole-containing proteins are one of the most fundamental classes of enzymes in
nature and it remains an open question to give a chemical rationale for the multitude of …

During photosynthesis carotenoids normally serve as antenna pigments, transferring singlet
excitation energy to chlorophyll, and preventing singlet oxygen production from chlorophyll …

Photosynthesis is one of the first natural processes evolved by cyanobacteria, algae and
green plants to trap light and CO 2 in the form of reduced carbon compounds while …

Based on the structural analysis of photosystem II of Thermosynechococcus elongatus, a
detailed calculation of optical properties of reaction-center (D1–D2) complexes is presented …

We propose an exciton model for the Photosystem II reaction center (RC) based on a
quantitative simultaneous fit of the absorption, linear dichroism, circular dichroism, steady …

Exciton charge separation in photosynthetic reaction centers from purple bacteria (PbRC)
and photosystem II (PSII) occurs exclusively along one of the two pseudo-symmetric …

The theoretical description of the initial steps in photosynthesis has gained increasing
importance over the past few years. This is caused by more and more structural data …

Absorbance difference spectra associated with the light-induced formation of functional
states in photosystem II core complexes from Thermosynechococcus elongatus and …
