Plastidic type I signal peptidase 1 is a redox-dependent thylakoidal processing peptidase

Jieping Zhu

Thylakoids are the photosynthetic membranes in chloroplasts and cyanobacteria. The aqueous phase inside the thylakoid known as the thylakoid lumen plays an essential role in the photosynthetic electron transport. The presence and significance of thiol-disu ...

Control of Mitochondrial pH by Uncoupling Protein 4 in Astrocytes Promotes Neuronal Survival

Pierre Magistretti, Hélène Danielle Perreten Lambert, Sylvain Eric Lengacher, Manuel Raphael Zenger, Jean-Yves Chatton

Brain activity is energetically costly and requires a steady and highly regulated flow of energy equivalents between neural cells. It is believed that a substantial share of cerebral glucose, the major source of energy of the brain, will preferentially be ...

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 ...

Delayed bactericidal response of Mycobacterium tuberculosis to bedaquiline involves remodelling of bacterial metabolism

John McKinney, Neeraj Dhar, Muhittin Emre Özdemir, Ping Lu

Bedaquiline (BDQ), an ATP synthase inhibitor, is the first drug to be approved for treatment of multidrug-resistant tuberculosis in decades. Though BDQ has shown excellent efficacy in clinical trials, its early bactericidal activity during the first week o ...

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 ...

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 ...
