Cryo-electron microscopy of membrane proteins

Henning Paul-Julius Stahlberg

Electron crystallography is used to study membrane proteins in the form of planar, two-dimensional (2D) crystals, or other crystalline arrays such as tubular crystals. This method has been used to determine the atomic resolution structures of bacteriorhodo ...

Activation and Spatial Organization of the Adenosine A2A Receptor in Supported Plasma Membrane Sheets

Sophie Roizard

G protein-coupled receptors (GPCRs) are ubiquitous mediators of signal transduction across cell membranes and constitute a very important class of therapeutic targets. The main mechanisms involving GPCR activation and signal transduction to the cell interi ...

Molecular Modeling of Membrane Embedded Proteins

Thomas Lemmin

Over the past years, molecular modeling and simulation techniques have had a major impact on experimental life sciences. They are capable of providing accurate insight into microscopic mechanisms, which are usually difficult to investigate experimentally. ...

A Biochemical and Biophysical Investigation of 5-HT3 Receptor Stability

Menno Berend Tol

The 5-hydroxytryptamine 3 receptor (5-HT3R) is a member of the pentameric ligand-gated ion channel (pLGIC) family, that plays an important role in fast signal transduction and cell-cell communication in synapses: They convert a chemical signal from a neuro ...

Projection Structure of the Secondary Citrate/Sodium Symporter CitS at 6 angstrom Resolution by Electron Crystallography

Henning Paul-Julius Stahlberg

CitS from Klebsiella pneumoniae acts as a secondary symporter of citrate and sodium ions across the inner membrane of the host. The protein is the best characterized member of the 2-hydroxycarboxylate transporter family, while no experimental structural in ...

Elsevier BV2012

Electron crystallography of membrane proteins uses cryo-transmission electron microscopy to record images and diffraction patterns of frozen-hydrated 2D crystals. Each two-dimensional (2D) crystal is only imaged once, at one specific tilt angle, and the re ...

Humana Press2012

Electron crystallography of membrane proteins records images and diffraction patterns of frozen-hydrated two-dimensional (2D) crystals. To reconstruct the high-resolution three-dimensional (3D) structure of a membrane protein, a multitude of images of 2D c ...

Phage Pierces the Host Cell Membrane with the Iron-Loaded Spike

Petr Leiman, Christopher Browning

Bacteriophages with contractile tails and the bacterial type VI secretion system have been proposed to use a special protein to create an opening in the host cell membrane during infection. These proteins have a modular architecture but invariably contain ...

Automatic recovery of missing amplitudes and phases in tilt-limited electron crystallography of two-dimensional crystals

Henning Paul-Julius Stahlberg

Electron crystallography of 2D protein crystals provides a powerful tool for the determination of membrane protein structure. In this method, data is acquired in the Fourier domain as randomly sampled, uncoupled, amplitudes and phases. Due to physical cons ...

Folding and Structure of the Pore Forming Toxin Aerolysin

Mircea Ioan Iacovache

The first obstacle encountered by a bacterial pathogen once inside the host is the plasma membrane surrounding the target cells. Throughout evolution bacteria has acquired and maintained genes that upon stimulation express proteins capable of damaging the ...
