• PubMed Abstract: 
  

  As part of a protein engineering study, the X-ray crystal structure of recombinant pig myoglobin, prepared and crystallized from E. coli, has been determined. Diffraction data were collected to 2.5 A spacing using a synchrotron X-ray source. The structure was solved using the molecular-replacement method and refined using least-squares minimization procedures to a crystallographic R factor of 18.5% using 14,481 reflections between 10 and 2.5 A. A preliminary comparison of the structure of pig myoglobin with other myoglobin structures is presented.
