A MODEL FOR THE BASIC HELIX- LOOPHELIX MOTIF AND ITS SEQUENCE SPECIFIC RECOGNITION OF DNA

A three dimensional model of the basic Helix-Loop-Helix motif and its sequence specific recognition of DNA is described. The basic-helix I is modeled as a continuous ?-helix because no ?-helix breaking residue is found between the basic region and the first helix. When the basic region of the two peptide monomers are aligned in the successive major groove of the cognate DNA, the hydrophobi...

Structural Determinants for Specific Recognition

DNA glycosylases catalyze the scission of the N-glycosyl bond linking either a damaged or mismatched base to the DNA sugar phosphate backbone. T4 endonuclease V is a glycosylase/apurinic (AP) lyase that is specific for UV light-induced cis-syn pyrimidine dimers. As a proposed transition state analog/inhibitor for glycosylases, a phosphoramidite derivative containing a pyrrolidine residue has be...

The helix-hairpin-helix DNA-binding motif: a structural basis for non- sequence-specific recognition of DNA

One, two or four copies of the 'helix-hairpin-helix' (HhH) DNA-binding motif are predicted to occur in 14 homologous families of proteins. The predicted DNA-binding function of this motif is shown to be consistent with the crystallographic structure of rat polymerase beta, complexed with DNA template-primer [Pelletier, H., Sawaya, M.R., Kumar, A., Wilson, S.H. and Kraut, J. (1994) Science 264, ...

Structural aspects of protein - DNA recognition Paul

Protein-DNA interactions are involved in many of the fundamental processes that occur inside cells, including packaging, replication, recombination, restriction and transcription. It is therefore vitally important to understand the nature of proteinDNA interactions, as they are so intimately linked to the control of gene expression, cell division and differentiation. Many proteins, particularly...

Structural basis for DNA recognition by STAT6.

STAT6 participates in classical IL-4/IL-13 signaling and stimulator of interferon genes-mediated antiviral innate immune responses. Aberrations in STAT6-mediated signaling are linked to development of asthma and diseases of the immune system. In addition, STAT6 remains constitutively active in multiple types of cancer. Therefore, targeting STAT6 is an attractive proposition for treating related...
