1A7S - PubMed Abstract: 
Crystals of human heparin binding protein (HBP) diffract to 1.1 A when flash-frozen at 120 K. The atomic resolution structure has been refined anisotropically using SHELXL96. The final model of HBP consists of 221 amino-acid residues of 225 possible, three glycosylation units, one chloride ion, 15 precipitant ethanol molecules and 323 water molecules. The structure is refined to a final crystallographic R factor of 15.9% and Rfree(5%) of 18.9% using all data. A putative protein kinase C activation site has been identified, involving residues 113-120. The structure is compared to the previously determined 2.3 A resolution structure of HBP.
