Notes:
Embryonic development in metazoa, to a significant extent, is directed by genes which contain a conserved sequence motif named the homeobox. This sequence encodes a polypeptide called the homeodomain which has sequence specific DNA-binding activity. We report the purification, crystallization, and preliminary diffraction analysis of the Drosophila Even-skipped homeodomain (Eve HD) bound to two different oligonucleotides. Crystals of Eve HD complexed with an AT-rich sequence belong to space group P21, a = 34.06, b = 61.61, c = 39.99 Å, b=90.0°. These crystals diffract to at least 2.0 Å and both native and derivative data sets have been collected. Crystals of Eve HD complexed with a GC-rich sequence belong to space group P63, a = b = 124.52, c = 66.78 Å and diffract to 3.5 Å resolution. A native data set has been collected. © 1995 Wiley-Liss, Inc.
