Integration host factor: putting a twist on protein–DNA recognition

TW Lynch, EK Read, AN Mattis, JF Gardner… - Journal of molecular …, 2003 - Elsevier
Integration host factor (IHF) is a DNA–bending protein that recognizes its cognate sites
through indirect readout. Previous studies have shown that binding of wild-type (WT)-IHF is …

A good turn for DNA: the structure of integration host factor bound to DNA

T Ellenberger, A Landy - Structure, 1997 - cell.com
The crystal structure of integration host factor (IHF) complexed with DNA shows how a small
heterodimeric protein can induce a big bend in DNA. IHF exerts leverage in the minor …

Crystal structure of an IHF-DNA complex: a protein-induced DNA U-turn

PA Rice, S Yang, K Mizuuchi, HA Nash - Cell, 1996 - cell.com
Integration host factor (IHF) is a small heterodimeric protein that specifically binds to DNA
and functions as an architectural factor in many cellular processes in prokaryotes. Here, we …

DNA bending and twisting properties of integration host factor determined by DNA cyclization

B Teter, SD Goodman, DJ Galas - Plasmid, 2000 - Elsevier
The binding of many proteins to DNA is profoundly affected by DNA bending, twisting, and
supercoiling. When protein binding alters DNA conformation, interaction between inherent …

Characterization of a set of integration host factor mutants deficient for DNA binding

AE Granston, HA Nash - Journal of molecular biology, 1993 - Elsevier
Integration host factor, IHF, is a sequence-specific DNA-binding and DNA-bending protein
composed of two related but non-identical subunits. We report the isolation and …

In vitro selection of integration host factor binding sites

SD Goodman, NJ Velten, Q Gao, S Robinson… - Journal of …, 1999 - Am Soc Microbiol
Integration host factor (IHF) is a bacterial protein that binds and severely bends a specific
DNA target. IHF binding sites are approximately 30 to 35 bp long and are apparently divided …

Single base-pair precision and structural rigidity in a small IHF-induced DNA loop

SE Nunes-Düby, LI Smith-Mungo, A Landy - Journal of molecular biology, 1995 - Elsevier
The prokaryotic integration host factor (IHF) is a DNA-binding protein that binds to specific
DNA sites as a heterodimer. Genetic and mutational analyses have previously identified …

Specific photocrosslinking of DNA-protein complexes: identification of contacts between integration host factor and its target DNA.

Azide moieties have been specifically placed in the backbone of DNA by chemical coupling
between azidophenacyl bromide and uniquely positioned phosphorothioate residues. The …

Two-step interrogation then recognition of DNA binding site by Integration Host Factor: an architectural DNA-bending protein

Y Velmurugu, P Vivas, M Connolly… - Nucleic acids …, 2018 - academic.oup.com
The dynamics and mechanism of how site-specific DNA-bending proteins initially interrogate
potential binding sites prior to recognition have remained elusive for most systems. Here we …
