dc.description.abstractThis study describes an affinity chromatography procedure for proteinase purification using bioselective binding to immobilized bacitracin. By coupling bacitracin to controlled-pore glass (CPG) beads, an affinity matrix was obtained that permitted rapid purification of proteinases under conditions that minimize autolysis. Bacitracin-CPG was used to bioselectively adsorb the extracellular proteinase secreted by Enterococcus faecalis var. liquefaciens IFPL 383. The overall purification obtained with this procedure was 5149-fold. The ability of bacitracin-CPG to bind other proteinases was examined using various commercial proteinases. The specific activities of subtilin BPN' and proteinase K were increased by bioselective adsorption and excellent recoveries of all proteinases applied were obtained.-
