Abstract
1,3-Propanediol dehydrogenase (1,3-PD-DH), encoded by the dhaT gene, is a key enzyme in the dissimilation process for converting glycerol to 1,3-propanediol in the human pathogen Klebsiella pneumoniae. Single colourless crystals were obtained from a recombinant preparation of 1,3-propanediol dehydrogenase overexpressed in Escherichia coli. The crystals belong to space group P2(1), with unit-cell parameters a = 91.9, b = 226.6, c = 232.6 A, beta = 92.9 degrees. The crystals probably contain two decamers in the asymmetric unit, with a V(M) value of 3.07 A3 Da(-1) and an estimated solvent content of 59%. Diffraction data were collected to 2.7 A resolution using synchrotron radiation at the ID14-4 beamline of the European Synchrotron Radiation Facility.
