Ultrafast Tryptophan-to-Heme Electron Transfer in Myoglobins Revealed by UV 2D Spectroscopy

Majed Chergui, Frank van Mourik, Cristina Consani

Tryptophan is commonly used to study protein structure and dynamics, such as protein folding, as a donor in fluorescence resonant energy transfer (FRET) studies. By using ultra-broadband ultrafast two-dimensional (2D) spectroscopy in the ultraviolet (UV) a ...

Near-Infrared 808 nm Light Boosts Complex IV-Dependent Respiration and Rescues a Parkinson-Related pink1 Model

Hubert van den Bergh, Georges Wagnières, Blaise Lovisa, Alec Ginggen

Mitochondrial electron transport chain (ETC) defects are observed in Parkinson's disease (PD) patients and in PD fly- and mouse-models; however it remains to be tested if acute improvement of ETC function alleviates PD-relevant defects. We tested the hypot ...

MicroRNA-22 (miR-22) Overexpression Is Neuroprotective via General Anti-Apoptotic Effects and May also Target Specific Huntington's Disease-Related Mechanisms

Ana Jovicic

Background: Whereas many causes and mechanisms of neurodegenerative diseases have been identified, very few therapeutic strategies have emerged in parallel. One possible explanation is that successful treatment strategy may require simultaneous targeting o ...

Bioavailable copper modulates oxidative phosphorylation and growth of tumors

Johan Auwerx, Douglas Hanahan, Pénélope Andreux, Carole Poitry-Yamate, Seiko Ishida

Copper is an essential trace element, the imbalances of which are associated with various pathological conditions, including cancer, albeit via largely undefined molecular and cellular mechanisms. Here we provide evidence that levels of bioavailable copper ...

Identification and characterization of proteins supporting dehalorespiration in Desulfitobacterium hafniense strain TCE1

Laure Prat

Respiration is a fundamental catalytic process in the aerobic and anaerobic energy metabolism of many prokaryotic and most eukaryotic organisms. The major difference between these organisms is that various organic and inorganic substrates can be used to do ...

Modulation of heme redox potential in the cytochrome c6 family

Cytochrome c6A is a unique dithio-cytochrome of green algae and plants. It has a very similar core structure to that of bacterial and algal cytochromes c6 but is unable to fulfill the same function of transferring electrons from cytochrome f to photosystem ...

Structure of cytochrome c6A, a novel dithio-cytochrome of Arabidopsis thaliana, and its reactivity with plastocyanin: implications for function

Cytochrome c6A is a unique dithio-cytochrome present in land plants and some green algae. Its sequence and occurrence in the thylakoid lumen suggest that it is derived from cytochrome c6, which functions in photosynthetic electron transfer between the cyto ...

Molecular characterization of key enzymes involved in dehalorespiration with tetrachloroethene

Julien Maillard

Chloroethenes, and most particularly tetra- (PCE) and trichloroethene (TCE) are major groundwater pollutants due to their extensive industrial use as solvents since the 1920s. The strong electronegativity of the chlorines renders them very stable under aer ...
