== Publication Abstract from PubMed ==
DNA ligases join single-strand breaks in double-stranded DNA by catalyzing the formation of a phosphodiester bond between adjacent 5'-phosphate and 3'-hydroxyl termini. Their function is essential to maintain the integrity of the genome in DNA replication, recombination and repair. A recombinant ATP-dependent DNA ligase from the hyperthermophilic anaerobic archaeon Thermococcus sibiricus was expressed in Escherichia coli and purified. Crystals were grown by vapour diffusion using the hanging-drop method with 17%(w/v) PEG 4000 and 8.5%(v/v) 2-propanol as precipitants. A diffraction experiment was performed with a single crystal, which diffracted X-rays to 3.0 A resolution. The crystal belonged to space group P2(1)2(1)2(1), with unit-cell parameters a = 58.590, b = 87.540, c = 126.300 A.
