Detailed Instructions: In this task, you are given an abstract of article. Your task is to generate title for this article. Preferred titles are under thirty words.
Q: 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 / 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 bend. The transcription factor fold is very similar to the structure of histone H5. In its amino-terminal half, three -helices adopt a compact structure that presents the third helix to the major groove. The remainder of the protein includes a twisted, antiparallel -structure and random coil that interacts with the minor groove.
A:
Co-crystal structure of the HNF-3/fork head DNA-recognition motif resembles histone H5
