Towards artificial methanogenesis: biosynthesis of the [Fe]-hydrogenase cofactor and characterization of the semisynthetic hydrogenase

The greenhouse gas and energy carrier methane is produced on Earth mainly by methanogenic archaea. In the hydrogenotrophic methanogenic pathway the reduction of one CO2 to one methane molecule requires four molecules of H-2 containing eight electrons. Four ...

Computational Investigation of Intracellular Signalling Cascades

Siri Camee van Keulen

In order to adjust to changes in the environment, cells can communicate via signalling cascades. A common pathway for intercellular communication is the G-protein-coupled- receptor (GPCR) signal transduction cascade which is triggered by a (chemical or phy ...

A scaffold protein connects type IV pili with the Chp chemosensory system to mediate activation of virulence signaling in Pseudomonas aeruginosa

Alexandre Louis André Persat, Joanne Netter Engel

Type IV pili (TFP) function as mechanosensors to trigger acute virulence programs in Pseudomonas aeruginosa. On surface contact, TFP retraction activates the Chp chemosensory system phosphorelay to upregulate 3', 5'-cyclic monophosphate (cAMP) production a ...

Real-time visualization of conformational changes within single MloK1 cyclic nucleotide-modulated channels

Henning Paul-Julius Stahlberg

Eukaryotic cyclic nucleotide-modulated (CNM) ion channels perform various physiological roles by opening in response to cyclic nucleotides binding to a specialized cyclic nucleotide-binding domain. Despite progress in structure-function analysis, the confo ...

Biomechanical forces promote blood development through prostaglandin E2 and the cAMP-PKA signaling axis

Olaia Maria Naveiras Torres-Quiroga, Nan Li

Blood flow promotes emergence of definitive hematopoietic stem cells (HSCs) in the developing embryo, yet the signals generated by hemodynamic forces that influence hematopoietic potential remain poorly defined. Here we show that fluid shear stress endows ...

Generation of photoswitchable peptide ligands by phage display

Silvia Bellotto

Photoswitchable ligands are used to control and study complex biological systems such as folding of proteins and peptides, enzymatic reactions or neuronal signaling. They are typically developed by conjugating photochromic compounds to known ligands so tha ...

The Crystal Structures of Apo and cAMP-Bound GlxR from Corynebacterium glutamicum Reveal Structural and Dynamic Changes upon cAMP Binding in CRP/FNR Family Transcription Factors

Stewart Cole, Florence Pojer

The cyclic AMP-dependent transcriptional regulator GlxR from Corynebacterium glutamicum is a member of the super-family of CRP/FNR (cyclic AMP receptor protein/fumarate and nitrate reduction regulator) transcriptional regulators that play central roles in ...

Intrinsic viscoelasticity increases temperature in knee cartilage under physiological loading

Dominique Pioletti, Philippe Abdel Sayed, Mohamadreza Nassajian Moghadam

Metabolism of proteoglycans and hyaluronic acid has been shown to be temperature- dependent in cartilage explants, with optimal anabolic effects between 36 1C and 38 1C. At rest, the temperature of human knee has a value of around 33 1C. We aim to show in ...

Regulatory elements involved in the expression of competence genes in naturally transformable Vibrio cholerae

Melanie Blokesch, Mirella Lo Scrudato

BackgroundThe human pathogen Vibrio cholerae normally enters the developmental program of natural competence for transformation after colonizing chitinous surfaces. Natural competence is regulated by at least three pathways in this organism: chitin sensing ...

Cell intrinsic immunity spreads to bystander cells via the intercellular transfer of cGAMP

Andrea Ablasser

The innate immune defence of multicellular organisms against microbial pathogens requires cellular collaboration. Information exchange allowing immune cells to collaborate is generally attributed to soluble protein factors secreted by pathogen-sensing cell ...
