              <xsd:documentation xml:lang="en">Details of the electron diffraction experiment THE MODEL WAS DERIVED USING ELECTRON DIFFRACTION AND IMAGE DATA FROM TWO DIMENSIONAL CRYSTALS OF TUBULIN INDUCED BY THE PRESENCE OF ZN++ IONS. WHAT FOLLOWS ARE THE COORDINATES FOR THE AB-TUBULIN DIMER BOUND TO TAXOL AS OBTAINED BY ELECTRON CRYSTALLOGRAPHY OF ZINC-INDUCED SHEETS. THIS IS THE UNREFINED MODEL, BUILT INTO A RAW DENSITY MAP WHERE THE RESOLUTION IN THE PLANE OF THE SHEET WAS 3.7 ANGSTROMS AND THAT PERPENDICULAR TO THE SHEET ABOUT 4.8 ANGSTROMS. THE MODEL DOES NOT CONTAIN MOST OF THE C-TERMINAL RESIDUES OF EITHER MONOMER WHICH WERE DISORDERED IN THE MAP. THE LOOP BETWEEN HELIX H1 AND STRAND S2, AND THAT BETWEEN H2 AND S3 ARE PRESENT FOR COMPLETENESS BUT WERE BUILT INTO VERY WEAK DENSITY. GIVEN THE LIMITED RESOLUTION OF THE MAP, THE CONFORMATION OF THE SIDE CHAINS, ESPECIALLY THOSE CORRESPONDING TO RESIDUES ON THE SURFACE OF THE DIMER, MUST BE TAKEN CAUTIOUSLY. IN ADDITION, BECAUSE THIS IS AN UNREFINED MODEL, CERTAIN GEOMETRY ERRORS MAY STILL BE PRESENT IN THE STRUCTURE. PLEASE TAKE THIS INTO ACCOUNT WHEN INTERPRETING YOUR OWN DATA BASED ON THE PRESENT TUBULIN STRUCTURE. ALTHOUGH THE POSITION OF RESIDUES (WITH THE EXCEPTION OF THOSE IN THE LOOPS MENTIONED ABOVE) SHOULD NOT CHANGE SIGNIFICANTLY UPON REFINEMENT, DRAWING INFORMATION AT THE LEVEL OF SIDE CHAIN CONFORMATION IS CLEARLY NOT ADVISED. FINALLY, PLEASE NOTICE THAT THE TAXOID IN THE MODEL IS THE TAXOL DERIVATIVE TAXOTERE. 1</xsd:documentation>
