| + | == Publication Abstract from PubMed == | ||
| + | The 1.75 A crystal structure of the Kluyveromyces lactis heat shock transcription factor (HSF) DNA-binding domain (DBD) complexed with DNA reveals a protein-DNA interface with few direct major groove contacts and a number of phosphate backbone contacts that are primarily water-mediated interactions. The DBD, a 'winged' helix-turn-helix protein, displays a novel mode of binding in that the 'wing' does not contact DNA like all others of that class. Instead, the monomeric DBD, which crystallized as a symmetric dimer to a pair of nGAAn inverted repeats, uses the 'wing' to form part of the protein-protein contacts. This dimer interface is likely important for increasing the DNA-binding specificity and affinity of the trimeric form of HSF, as well as for increasing cooperativity between adjacent trimers. | ||
