Abstract:
Two fragments of the C-terminal catalytic domain of human poly(ADP-ribose) polymerase (catPARP), Met-catPARP and Gly-Ser-catPARP, were purified and crystallized. Both catPARP crystals belong to space group C2, with almost the same unit-cell parameters. However, the shapes and harvest periods of both crystals were quite different owing to the slight mutation at the N-terminal position. Gly-Ser-catPARP was found to be more suitable for X-ray crystallography and crystals showed diffraction to at least 3.5 A resolution.
