1HCR - PubMed Abstract: 
The structure of the 52-amino acid DNA-binding domain of the prokaryotic Hin recombinase, complexed with a DNA recombination half-site, has been solved by x-ray crystallography at 2.3 angstrom resolution. The Hin domain consists of a three-alpha-helix bundle, with the carboxyl-terminal helix inserted into the major groove of DNA, and two flanking extended polypeptide chains that contact bases in the minor groove ...
