Crystallization and preliminary x-ray data for glucose-6-phosphate dehydrogenase from Leuconostoc mesenteroides.

The enzyme glucose-6-phosphate dehydrogenase from Leuconostoc mesenteroides has been crystallized from phosphate buffer in a form suitable for x-ray crystallographic studies. The crystals diffract to better than 2.4 A. The spacegroup is P3121 (P3221) a = 105.8 A, c = 225.1 A, V = 2.18 X 10(6) A3. The asymmetric unit probably contains a single dimer.
