An essential thioredoxin is involved in the control of the cell cycle in the bacterium Caulobacter crescentus

Thioredoxins (Trxs) are antioxidant proteins that are conserved among all species. These proteins have been extensively studied and perform reducing reactions on a broad range of substrates. Here, we identified Caulobacter crescentus Trx1 (CCNA_03653; CcTr ...

Impact of molecular flexibility on the site energy shift of chlorophylls in Photosystem II

Daniele Narzi, Leonardo Guidoni, Marco Manzoli

Light harvesting from the Sun by antenna complexes surrounding the reaction center of Photosystem II represents the first step of the natural oxygenic photosynthesis performed by plants, algae and cyanobacteria. The excitation energy derived from the sunli ...

Classical Force Fields Tailored for QM Applications: Is It Really a Feasible Strategy?

Oliviero Andreussi

Classical molecular dynamics is more and more often coupled to quantum mechanical based techniques as a statistical tool to sample configurations of molecular systems embedded in complex environments. Nonetheless, the classical potentials describing the mo ...

The ultrastructure of Chlorobaculum tepidum revealed by cryo-electron tomography

Henning Paul-Julius Stahlberg

Chlorobaculum (Cba) tepidum is a green sulfur bacterium that oxidizes sulfide, elemental sulfur, and thiosulfate for photosynthetic growth. As other anoxygenic green photosynthetic bacteria, Cba tepidum synthesizes bacteriochlorophylls for the assembly of ...

Molecular Architecture of Plant Thylakoids under Physiological and Light Stress Conditions: A Study of Lipid-Light-Harvesting Complex II Model Membranes

Giovanni Dietler, Andrzej Kulik

In this study, we analyzed multibilayer lipid-protein membranes composed of the photosynthetic light-harvesting complex II (LHCII; isolated from spinach [Spinacia oleracea]) and the plant lipids monogalcatosyldiacylglycerol and digalactosyldiacylglycerol. ...

Carbon nanotubes quench singlet oxygen generated by photosynthetic reaction centers

László Forró, Arnaud Magrez, Endre Horvath, Klara Hernadi, Krisztina Nagy

Photosensitizers may convert molecular oxygen into reactive oxygen species (ROS) including, e.g., singlet oxygen (O-1(2)), superoxide anion (O-2(-center dot)), and hydroxyl radicals ((OH)-O-center dot), chemicals with extremely high cyto- and potential gen ...

Light-induced rearrangements of chemisorbed dyes on anatase(101)

Ulf Anders Hagfeldt

Photoinduced mol. rearrangements are important in daily events essential for life such as visual perception and photo-protection of light harvesting complexes in plants. In this study we demonstrate that similar photorearrangements appear in an analogous t ...
