Notes:
A description is given of the preparation and properties of four water-insoluble papain derivatives by three different techniques: (a) covalent binding to a water-insoluble diazoimitn salt derived from a copolymer of p-aminophenylalanine and leucine; (b) binding to insoluble preparations of collagen via bisdiazobenzidine-2,2′-disulfonic acid; (c) in-solubilization by crosslinking the enzyme itself with bisdiazobenzidine. By all three methods it, was possible to obtain stable water-insoluble papain derivatives retaining much of the activity of the native enzyme on low and high molecular weight substrates.
