Purification procedure for dipeptidyl peptidase III (DPP III) from human erythrocytes cytosol, entailing separations on DEAE-cellulose, hydroxylapatite and Sephacryl S-200 column, which gave homogeneous preparation in 35% yield, is described. The enzyme was shown to be a monomeric acidic protein (Mr approximately 82,000, pI approximately 4.5-4.6), sensitive to freezing and temperatures above 40 degrees C. It was inhibited by metallo-chelators and sulphydryl reagents, the activity being restored… CONTINUE READING
