Abstract

The three dimensional structures of pHSA and rHSA triclinic crystals were determined at 2.5A°resolution through multiple isomorphous replacement with a known tetragonal crystal. The pHSA and rHSA structures are similar with an r.m.s deviation of 0.24 A° for all the cα atoms. Cys 34 does not have a disulfide link with any ligand. A pocket of hydrophobic and positively charged residues is formed at domains 2 and 3 where a wide range of compounds can be accommodated. The surface of the domain has three binding sites for long chain fatty acids.
