Uridine diphosphoglucose pyrophosphorylase was purified 2500-fold from rabbit skeletal muscle with a total recovery of 35% of the initial activity. The present procedure was made possible by an extensive use of hydrophobic chromatography. Purified pyrophosphorylase had a specific activity of 500 mumol/min/mg of protein and was homogeneous by chromatographic and electrophoretic criteria. The enzyme appears to be composed of eight subunits of 53,000 molecular weight each.
