A series of Cu(diimine)(X-sal)(NO3) complexes, where the diimine is either 2,2'-bipyridine (bpy) or 1,10-phenanthroline (phen) and X-sal is a monoanionic halogenated salicylaldehyde (X = Cl, Br, I, or H), have been synthesized and characterized by elementa ...

Retrieving high-resolution information from disordered 2D crystals by single-particle cryo-EM

Henning Paul-Julius Stahlberg

Electron crystallography can reveal the structure of membrane proteins within 2D crystals under close-to-native conditions. High-resolution structural information can only be reached if crystals are perfectly flat and highly ordered. In practice, such crys ...

Springer Nature2019

Inspired by the preferential, allosteric binding of RAPTA-T and auranofin to the nucleosome core particle, we describe the design and synthesis of a series of heterobimetallic ruthenium(II)-gold(I) complexes with varying spacer lengths ranging from four to ...

Recent evidence suggests involvement of biometal homeostasis in the pathological mechanisms in Alzheimer's disease (AD). For example, increased intracellular copper or zinc has been linked to a reduction in secreted levels of the AD-causing amyloid- peptid ...

Amer Soc Biochemistry Molecular Biology Inc2017

Realistic models of cellular environments have long captured the imagination of biologists and physical scientists. More than 20 years ago, Goodshellâs inspiring rendering of cellular environments provided the foundation for the idea of capturing the ful ...

Alzheimer s disease (AD) is a devastating neurodegenerative disease characterized by strong cognitive impairment and memory loss. These symptoms are caused by neuronal death, induced by two pathological hallmarks: extracellular senile plaques composed of a ...

gamma-Secretase is a multi-subunit membrane protease complex that catalyses the final intramembrane cleavage of the beta-amyloid precursor protein (APP) during the neuronal production of amyloid-beta peptides (A beta), which are implicated as the causative ...

Electron crystallography of two-dimensional (2D) crystals determines the structure of membrane proteins in the lipid bilayer by imaging with cryo-electron microscopy and image processing. Membrane proteins can be packed in regular 2D arrays by their recons ...

Alzheimer's disease (AD)-associated gamma-secretase is a ubiquitously expressed multi-subunit protease complex embedded in the lipid bilayer of cellular compartments including endosomes and the plasma membrane. Although gamma-secretase is of crucial intere ...

beta-Barrel pore-forming toxins (beta-PFT), a large family of bacterial toxins, are generally secreted as water-soluble monomers and can form oligomeric pores in membranes following proteolytic cleavage and interaction with cell surface receptors. Monalysi ...
