THESE DISTANCES SHOULD BE REGARDED AS ...Details: AMIDE HYDROGEN BOND LENGTHS IN THE PRESENT MODEL CLUSTER ABOUT 0.86 ANGSTROMS AND AROMATIC CARBON HYDROGEN DISTANCES CLUSTER ABOUT 0.96 ANGSTROMS. THESE DISTANCES SHOULD BE REGARDED AS PRELIMINARY RESULTS, PENDING FURTHER ANALYSIS. RESIDUE PRO 168 IS A CIS PROLINE. RESIDUE CA 276 CA IS A CALCIUM ++ ION RESIDUE CA 277 CA REFINED AS CALCIUM ++ ION HAS LOW OCCUPANCY AND IS PROBABLY ANOTHER CATION, POSSIBLY POTASSIUM RESIDUE SO4 278 IS A SULFATE ION. RESIDUE GOL 301 IS A GLYCEROL MOLECULE. A SPECIAL HYDROGEN BOND EXISTS BETWEEN ASP 32 OD2 AND HIS 64 ND1. THIS HYDROGEN ATOM IS SHARED BETWEEN THESE RESIDUES. THE POSITION IS ESTIMATED FROM THE PEAK FOR THIS ATOM IN A FO-FC DIFFERENCE ELECTRON DENSITY MAP. THIS HYDROGEN ATOM HAS BEEN DESIGNATED AS HD1 OF HIS 64 TO CONFORM TO THE PDB NOMENCLATURE.
