Kleptoplasty in a shallow water benthic foraminifer, Haynesina germanica

Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

Some benthic foraminifera have the ability to incorporate functional chloroplasts from diatoms (kleptoplasty). Our objective was to investigate kleptoplast cellular organisation, functionality (O2 flux, C and N incorporation), pigment composition and photo ...

PSII-LHCII Supercomplex Organizations in Photosynthetic Membrane by Coarse-Grained Simulation

Berend Smit

Green plant Photosystem II (PSII) and light-harvesting complex II (LHCLI) in the stacked grana regions of thylakoid membranes can self-organize into various PSII LHCII supercomplexes With crystalline Of fluid-like supramolecular structures to adjust themse ...

Translational arrest by a prokaryotic signal recognition particle is mediated by RNA interactions

Henning Paul-Julius Stahlberg

The signal recognition particle (SRP) recognizes signal sequences of nascent polypeptides and targets ribosome-nascent chain complexes to membrane translocation sites. In eukaryotes, translating ribosomes are slowed down by the Alu domain of SRP to allow e ...

Plant nanobionics approach to augment photosynthesis and biochemical sensing

Ardemis Anoush Boghossian

The interface between plant organelles and non-biological nanostructures has the potential to impart organelles with new and enhanced functions. Here, we show that single-walled carbon nanotubes (SWNTs) passively transport and irreversibly localize within ...

Nature Publishing Group2014

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 ...

Charge stabilization by reaction center protein immobilized to carbon nanotubes functionalized by amine groups and poly(3-thiophene acetic acid) conducting polymer

László Forró, Arnaud Magrez, Endre Horvath, Klara Hernadi

A large number of studies have indicated recently that photosynthetic reaction center proteins (RC) bind successfully to nanostructures and their functional activity is largely retained. The major goal of current research is to find the most efficient syst ...

Wiley-V C H Verlag Gmbh2012

The twin-arginine translocation (Tat) pathway is a protein targeting system present in many prokaryotes. The physiological role of the Tat pathway is the transmembrane translocation of fully-folded proteins, which are targeted by N-terminal signal peptides ...

Photosynthetic reaction center protein in nanostructures

László Forró, Arnaud Magrez, Klara Hernadi, Krisztina Nagy

Photosynthetic reaction center (RC) is one of the most important proteins, because it is Nature's solar battery converting light energy into chemical potential in the photosynthetic membrane assuring conditions for carbon reduction in cells. Although it is ...
