Two aspartic carboxyl groups act as key catalytic groups in the active site of an aspartic protease. We synthesized an aspartic protease analogue by positioning three salicylate residues in close proximity on a cross-linked polystyrene. The immobile artificial protease effectively hydrolyzed albumin into many small fragments by the catalytic action of carboxyl groups contained in the active site. The artificial protease manifested optimum activity at pH 3 just as aspartic proteases.
