Abstract

Coenzyme A is purified by a process involving contacting a cyanogen halide-activated water-insoluble polysaccharide with a cell-free extract of a coenzyme A-producing microorganism to immobilize proteins such as enzymes having affinity for coenzyme A on the polysaccharide. The immobilized proteins are then contacted with a coenzyme A-containing solution to absorb coenzyme A followed by eluting coenzyme A from the immobilized proteins. Alternatively, the proteins having affinity for coenzyme A may be isolated from the cell-free extract prior to immobilization by absorbing the proteins on coenzyme A immobilized on a cyanogen halide-activated water-insoluble polysaccharide followed by eluting the proteins from the immobilized coenzyme A.
