Synthesis and structural characterization of a mimetic membrane-anchored prion protein [PDF]

open access: yes, 2006
During pathogenesis of transmissible spongiform encephalopathies (TSEs) an abnormal form (PrPSc) of the host encoded prion protein (PrPC) accumulates in insoluble fibrils and plaques. The two forms of PrP appear to have identical covalent structures, but

Weak self-interactions of globular proteins studied by small-angle X-ray scattering and structure-based modeling

open access: yes, 2014
We investigate protein-protein interactions in solution by small-angle X-ray scattering (SAXS) and theoretical modeling. The structure factor for solutions of bovine pancreatic trypsin inhibitor (BPTI), myoglobin (Mb), and intestinal fatty acid-binding ...

Preliminary X-ray diffraction analysis of YqjH from Escherichia coli: a putative cytoplasmic ferri-siderophore reductase [PDF]

open access: yes, 2008
YqjH is a cytoplasmic FAD-containing protein from Escherichia coli; based on homology to ViuB of Vibrio cholerae, it potentially acts as a ferri-siderophore reductase.

Degenerate cysteine patterns mediate two redox sensing mechanisms in the papillomavirus E7 oncoprotein

open access: yesRedox Biology, 2017
Infection with oncogenic human papillomavirus induces deregulation of cellular redox homeostasis. Virus replication and papillomavirus-induced cell transformation require persistent expression of viral oncoproteins E7 and E6 that must retain their ...

RuvC uses dynamic probing of the Holliday junction to achieve sequence specificity and efficient resolution

open access: yesNature Communications, 2019
Holliday junctions (HJs) are four-way DNA structures that occur in DNA repair by homologous recombination which are removed by nucleases such as RuvC. Here the authors provide structural and biochemical details on the steps required for the completion of
