• PubMed Abstract: 
  

  A glutathione S-transferase fused with the nuclear matrix targeting signal (GST-NMTS) of AML-1/CBF-alpha2 has been crystallized by the vapor diffusion method using polyethylene glycol (PEG) as the precipitant. The NMTS is a 31-amino-acid signal peptide that can target the AML-1/CBF-alpha2 protein to the nuclear matrix. The crystal belongs to tetragonal space group P43212 with unit cell dimensions a = b = 93.4 A, c = 57.6 A. There is one GST-fusion protein per asymmetric unit. Crystals diffracted to at least 2.7 A and are appropriate for structure determination.
