    Safo M, Mathews I, Musayev F, di Salvo M, Thiel D, Abraham D, et al. X-ray structure of Escherichia coli pyridoxine 5'-phosphate oxidase complexed with FMN at 1.8 A resolution. Structure. 2000;8:751-62 pubmed
    ..This high-resolution E. coli PNPOx structure permits predictions to be made about residues involved in substrate binding and catalysis. These predictions provide testable hypotheses, which can be answered by making site-directed mutants...
  2. Safo M, Abraham D. The X-ray structure determination of bovine carbonmonoxy hemoglobin at 2.1 A resoultion and its relationship to the quaternary structures of other hemoglobin crystal froms. Protein Sci. 2001;10:1091-9 pubmed
    ..The constrained heme groups and the increased steric contact involving the CO ligand and the distal heme residues relative to human Hb may explain in part the low intrinsic oxygen affinity of bovine Hb. ..
  3. Safo M, Musayev F, di Salvo M, Schirch V. X-ray structure of Escherichia coli pyridoxine 5'-phosphate oxidase complexed with pyridoxal 5'-phosphate at 2.0 A resolution. J Mol Biol. 2001;310:817-26 pubmed publisher
    ..A possible tunnel exists between the two sites so that pyridoxal 5'-phosphate formed at the active site may transfer to the non-catalytic site without passing though the solvent...
