REMARK 5 REMARK 5 THESE COORDINATES REPRESENT A MODEL OF HUMAN BETA-CELL REMARK 5 GLUCOKINASE BUILT BY ANALOGY TO A REFINED 2.1 ANGSTROM REMARK 5 CRYSTAL STRUCTURE OF YEAST HEXOKINASE B. A DETAILED REMARK 5 DESCRIPTION OF THE CONSTRUCTION OF THIS MODEL IS PRESENTED REMARK 5 IN DIABETES 43, 784 - 791, 1994. BRIEFLY, THE AMINO ACID REMARK 5 SEQUENCES OF HUMAN BETA-CELL GLUCOKINASE AND YEAST REMARK 5 HEXOKINASE B WERE OPTIMALLY ALIGNED SUCH THAT INSERTIONS REMARK 5 AND DELETIONS WERE RESTRICTED TO REGIONS BETWEEN KNOWN REMARK 5 ELEMENTS OF SECONDARY STRUCTURE IN THE YEAST HEXOKINASE REMARK 5 CRYSTAL STRUCTURE. SIDE CHAIN ATOMS FOR NON-IDENTICAL REMARK 5 RESIDUES WERE THEN REPLACED WITH THOSE OF THE CORRESPONDING REMARK 5 RESIDUES IN THE GLUCOKINASE SEQUENCE, AND MANUALLY ADJUSTED REMARK 5 WHEN NECESSARY. INSERTIONS AND DELETIONS WERE MODELLED REMARK 5 AFTER 'TEMPLATE' PEPTIDE SEGMENTS SELECTED FROM CRYSTAL REMARK 5 STRUCTURES IN THE PROTEIN DATA BANK. THE RESULTING MODEL REMARK 5 WAS THEN SUBJECTED TO STEREOCHEMICALLY-RESTRAINED ENERGY REMARK 5 MINIMIZATION USING THE PROGRAM XPLOR VERSION 3.0. THE RMS REMARK 5 DIFFERENCE IN C-ALPHA POSITIONS BETWEEN THE FINAL REMARK 5 GLUCOKINASE MODEL AND YEAST HEXOKINASE CRYSTAL STRUCTURE IS REMARK 5 0.54 ANGSTROMS. THE MODEL INCLUDES COORDINATES FOR REMARK 5 RESIDUES 8 THROUGH 465 OF HUMAN GLUCOKINASE AND A SINGLE REMARK 5 BOUND GLUCOSE MOLECULE.
