Structure determination of glucose isomerase from Streptomyces murinus at 2.6 A resolution.
Glucose isomerase from Streptomyces murinus has been crystallized in space group P4(1)2(1)2, cell dimensions a = b = 137.65 and c = 132.20 A. One dimer of the tetrametric molecule is found per asymmetric unit. An initial structure solution was obtained by the molecular replacement method. The crystallographic refinement was performed using molecular dynamics techniques with X-ray restraints. The final crystallographic R value is 21.4% at 2.6 A resolution including 3023 non-H atoms, two metal ions and two water molecules per monomer.
