Abstract
Flap endonuclease 1 (FEN1) is a structure-specific nuclease that removes 5'-overhanging flaps in DNA repair and removes the RNA/DNA primer during maturation of the Okazaki fragment in lagging-strand DNA replication. FEN1 from the hyperthermophilic archaeon Desulfurococcus amylolyticus was expressed in Escherichia coli, purified and crystallized using the sitting-drop vapour-diffusion method with monoammonium dihydrogen phosphate as the precipitant at pH 8.3. X-ray diffraction data were collected to 2.00 A resolution. The space group of the crystal was determined as the primitive hexagonal space group P321, with unit-cell parameters a = b = 103.76, c = 84.58 A. The crystal contained one molecule in the asymmetric unit.
