You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMed DNA ligase IV catalyses the final ligation step in the non-homologous end-joining (NHEJ) DNA repair pathway and requires interaction of the ligase with the Xrcc4 'genome-guardian', an essential NHEJ factor. Here we report the 3.9 A crystal structure of the Saccharomyces cerevisiae Xrcc4 ortholog ligase interacting factor 1 (Lif1p) complexed with the C-terminal BRCT domains of DNA ligase IV (Lig4p). The structure reveals a novel mode of protein recognition by a tandem BRCT repeat, and in addition provides a molecular basis for a human LIG4 syndrome clinical condition. Structure of an Xrcc4-DNA ligase IV yeast ortholog complex reveals a novel BRCT interaction mode.,Dore AS, Furnham N, Davies OR, Sibanda BL, Chirgadze DY, Jackson SP, Pellegrini L, Blundell TL DNA Repair (Amst). 2006 Mar 7;5(3):362-8.
