== Publication Abstract from PubMed == | |||
The three-dimensional structure of an HNF-3/fork head DNA-recognition motif complexed with DNA has been determined by X-ray crystallography at 2.5 A resolution. This alpha/beta protein binds B-DNA as a monomer, through interactions with the DNA backbone and through both direct and water-mediated major and minor groove base contacts, inducing a 13 degrees bend. The transcription factor fold is very similar to the structure of histone H5. In its amino-terminal half, three alpha-helices adopt a compact structure that presents the third helix to the major groove. The remainder of the protein includes a twisted, antiparallel beta-structure and random coil that interacts with the minor groove. | |||
Co-crystal structure of the HNF-3/fork head DNA-recognition motif resembles histone H5.,Clark KL, Halay ED, Lai E, Burley SK Nature. 1993 Jul 29;364(6436):412-20. PMID:8332212<ref>PMID:8332212</ref> | |||
