crystallization communications
The enzyme transketolase from the lactic acid bacterium Lactobacillus salivarius (subsp. salivarius UCC118) has been recombinantly expressed and purified using an Escherichia coli expression system. Purified transketolase from L. salivarius has been crystallized using the vapour-diffusion technique. The crystals belonged to the trigonal space group P3221, with unit-cell parameters a = b = 75.43, c = 184.11 Å, and showed diffraction to 2.3 Å resolution.
