title: The application of triazine dye affinity chromatography to the large-scale purification of glycerokinase from Bacillus stearothermophilus.
abstract: Gram quantities of homogeneous glycerokinase have been prepared from the thermophilic bacterium, Bacillus stearothermophilus, using three major steps: precipitation of debris at pH 5.1, ion-exchange chromatography on DEAE-Sephadex, and affinity chromatography on Procion Blue MX-3G-Sepharose. This method is a considerable improvement over conventional techniques; the purified enzyme was obtained with a 40% recovery and a specific activity of 120 units (mumol/min)/mg protein. A modified culture medium enabled yields of 3.4 X 10(6) units of enzyme to be obtained from 400-liter production cultures.
