X-RAY DIFFRACTION	MOLECULAR REPLACEMENT	THROUGHOUT	unpublished model of complex between same protein and DNA fragment. That structure was solved by a combination of zinc-SAD (SHELXD/E) and molecular replacement in "density" mode (MOLREP), using ideal DNA (COOT) and human MLL2 (currently unpublished) as search models.	2.25	35	7736	351	99.781	0.221	0.2196	0.2502	RANDOM	70.547
