REMARK 400 DEPOSITED ARE COORDINATES FOR EPOTHILONE A BOUND REMARK 400 TO AB-TUBULIN DIMER IN THE ZINC-INDUCED SHEETS. REMARK 400 THE LIGAND MODEL WAS FIT INTO A DENSITY MAP FOR WHICH REMARK 400 THE RESOLUTION IN THE PLANE OF THE SHEET WAS 2.89 REMARK 400 ANGSTROMS AND THAT PERPENDICULAR TO THE SHEET WAS REMARK 400 ABOUT 4.2 ANGSTROMS AS DESCRIBED IN THE SUPPLEMENTAL REMARK 400 TEXT. REMARK 400 PROTEIN MODEL HAS NOT BEEN OPTIMIZED AT THE REMARK 400 RESOLUTION REPORTED IN REMARK 3 - SEE REMARK 400 WWW.ORGANIC.EMORY.EDU/EPO REMARK 400 R FREE REPORTED BY THE SOFTWARE ABOVE IS NOT RELEVANT. REMARK 400 PHASES WERE DERIVED FROM A PREVIOUS MODEL OF ALPHA/BETA REMARK 400 TUBULIN COMPLEXED WITH TAXOL (PDB ID 1JFF). REMARK 400 "SHAKING", HIGH TEMPERATURE ANNEALING, AND MODEL REMARK 400 AVERAGING WERE COMBINED TO PRODUCE AN OMIT MAP OF THE REMARK 400 BOUND EPOTHILONE THAT MINIMIZED SYSTEMATIC BIAS. A REMARK 400 NUMBER OF CONFORMATIONAL MODELS WERE FLEXIBLY FITTED REMARK 400 INTO THE INITIAL MAP AND TESTED AGAINST THE DIFFRACTIONS REMARK 400 BY DIFFERENCE MAP REFINEMENT AS DESCRIBED IN THE PRIMARY REMARK 400 REFERENCE. REMARK 400 REFINEMENT TO THE FINAL STRUCTURE WAS LIMITED WITHIN AN REMARK 400 8 A RADIUS OF THE LIGAND. ALTHOUGH THE REST OF THE REMARK 400 PROTEIN SHOWS LITTLE DEVIATION FROM THAT SEEN IN 1JFF, REMARK 400 CERTAIN RESIDUES DO NOT FULLY CONFORM TO RAMACHANDRAN REMARK 400 CHARACTERISTICS AND SHOULD BE REGARDED WITH CAUTION. THE REMARK 400 FINAL MAPS ASSOCIATED WITH THE PRESENT MODEL WERE DERIVED REMARK 400 BY RIGID FITTING OF THE MODELED COMPLEX. AS SUCH, FREE R REMARK 400 REPORTED BY THE SOFTWARE ABOVE IS NOT RELEVANT.
