Protein-RNA interactions: a structural analysis

open access: yes, 2001
A detailed computational analysis of 32 protein-RNA complexes is presented. A number of physical and chemical properties of the intermolecular interfaces are calculated and compared with those observed in protein-double-stranded DNA and protein-single ...

Protein-induced changes in DNA structure and dynamics observed with noncovalent site-directed spin-labeling and PELDOR

open access: yes, 2012
Site-directed spin labeling and pulsed electron–electron double resonance (PELDOR or DEER) have previously been applied successfully to study the structure and dynamics of nucleic acids. Spin labeling nucleic acids at specific sites requires the covalent

Genetic and biochemical identification of a novel single-stranded DNA binding complex in Haloferax volcanii

open access: yesFrontiers in Microbiology, 2012
Single-stranded DNA binding proteins play an essential role in DNA replication and repair. They use oligosaccharide-binding folds, a five-stranded ß-sheet coiled into a closed barrel, to bind to single-stranded DNA thereby protecting and stabilizing

Phosphoinositides and inositol phosphates as molecular glues

open access: yesFEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

Analysis of a hybrid TATA box binding protein originating from mesophilic and thermophilic donor organisms [PDF]

open access: yes, 2010
The TATA Box Binding Protein (TBP) is a 20 kD protein that is essential and universally conserved in eucarya and archaea. Especially among archaea, organisms can be found that live below 0°C as well as organisms that grow above 100°C.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Nuclear factor I genomic binding associates with chromatin boundaries [PDF]

open access: yes, 2013
BACKGROUND: The Nuclear Factor I (NFI) family of DNA binding proteins (also called CCAAT box transcription factors or CTF) is involved in both DNA replication and gene expression regulation.

Protein-DNA interaction in tight-binding paradigm

open access: yesScientific Reports
The interaction between protein and DNA across three distinct conformations of protein chains is examined in the framework of band structures and density of states analysis, utilizing a tight-binding Hamiltonian model in conjunction with Green’s function

Combination of native and denaturing PAGE for the detection of protein binding regions in long fragments of genomic DNA

open access: yesBMC Genomics, 2008
Background In a traditional electrophoresis mobility shift assay (EMSA) a 32P-labeled double-stranded DNA oligonucleotide or a restriction fragment bound to a protein is separated from the unbound DNA by polyacrylamide gel electrophoresis (PAGE) in ...
