The structure of bovine liver cytochrome b(5), a soluble 93-residue, proteolytic fragment of a 16 kDa membrane-bound hemoprotein, initially, solved at 2.0 A resolution, has been refined at 1.5 A using data collected, on a diffractometer. Refinement to 2.0 A resolution used the, Hendrickson-Konnert procedure PROLSQ and was then extended to 1.5 A, resolution using the program PROFFT. Only residues 3-87 could be, identified in the model and these residues together with 93 water, molecules gave an agreement factor of R = 0.161 for data in the resolution, range 1.5-5 A. The structure was finally refined using the program X-PLOR, which enabled alternate conformers to be modelled for several surface side, chains. Residues 1 and 2 at the amino terminus of the protein and residue, 88 near the carboxyl terminus could be identified from these, electron-density maps. However the remaining disordered carboxy-terminal, residues could not successfully be included in the model. A total of 117, solvent molecules were included in the final refinement to give R = 0.164, for the data between 1.5 and 10 A.
