Many macromolecules in the cell function by forming multi-component assemblies. We have applied the technique of small angle neutron scattering to study a nucleic acid-protein complex and a multi-protein complex. The results illustrate the versatility and ...
The twin-arginine transport (Tat) system is dedicated to the translocation of folded proteins across the bacterial cytoplasmic membrane. Proteins are targeted to the Tat system by signal peptides containing a twin-arginine motif. In Escherichia coli, many ...
Limited searching in the conformational space is one of the major obstacles for investigating protein dynamics by numerical approaches. For this reason, classical all-atom mol. dynamics (MD) simulations of proteins tend to be confined to local energy min., ...
A misfolded conformer of the cellular prion protein, denoted as scrapie prion protein, is considered responsible for a variety of fatal neurodegenerative diseases. Both, the function of the protein in its native conformation as well as the factors that tri ...
The inability to determine molecular structures from powdered samples is a key barrier to progress in many areas of molecular and materials science. We report an approach to structure determination that combines molecular modeling with experimental spin di ...
Chemoselective autoxidation of 4-imino-1,5-dimethyl-3-(4-nitrophenyl) imidazolidin-2-one (1b) to its 5-hydroxy derivative 2 occurred in solutions of DMSO-d(6), acetonitrile-d(3) or refluxing ethanol. Also bis(imidazolidin-5-yl) peroxide 5 was isolated as a ...
Nanofabricated pores in 20 nm-thick silicon nitride membranes were used to probe various protein analytes as well as to perform an antigen-antibody binding assay. A two-compartment electrochemical cell was separated by a single nanopore, 28 nm in diameter. ...
PDZ domains are typical examples of binding motifs mediating the formation of protein-protein assemblies in many different cells. A quantitative characterization of the mechanisms intertwining structure, chemistry, and dynamics with the PDZ function repres ...
Pore-forming toxins (PFTs) are the most common class of bacterial protein toxins and constitute important bacterial virulence factors. The mode of action of PFT is starting to be better understood. In contrast, little is known about the cellular response t ...
Good things come in small packages: For its moderate molecular weight, the metallostar complex [Fe{Gd2L(H2O)4}3]4− (see picture; L is a bipyridine–poly(aminocarboxylate) derivative) displays exceptionally high proton relaxivity, which is explained in terms ...
