THE MODEL WAS REMARK 3 REFINED TO 2.2 ANGSTROMS WITH THIS DATA SET AND REPORTED IN LIMA REMARK 3 (1994). THE MODEL WAS SUBSEQUENTLY TRANSFERRED TO REMARK 3 A 1.7 ANGSTROM DATA SET COLLECTED AT 0.9144 ANGSTROM REMARK 3 WAVELENGTH AT THE CORNELL HIGH ENERGY SYNCHROTRON SOURCE. THE REMARK 3 DATA WAS COLLECTED ON THE PRINCETON CCD DETECTOR. THE MODEL WAS REMARK 3 REFINED TO 1.9 ANGSTROM WITH THIS DATA. THE REMARK 3 COORDINATES THAT FOLLOW REPRESENT THIS REFINEMENT. A REMARK 3 TOTAL OF 24 SIMULATED ANNEALING OMIT MAPS WERE GENERATED TO COVER REMARK 3 THE ENTIRE STRUCTURE AT 1.9 ANGSTROM RESOLUTION.
