Crystal structures of the catalytic domain of human stromelysin-1 (MMP-3) and collagenase-3 (MMP-13) with a hydroxamic acid inhibitor SM-25453 have been solved at 2.01 and 2.37 A resolutions , respectively.
We used X-ray crystallography to determine two structures of the catalytic domain of human PARP2 : the complexes with PARP inhibitors 3-aminobenzamide and ABT-888.
