Homogeneity of the enzyme was shown with the methods of gel filtration and disc electrophoresis. The molecular mass of penicillinamidase (PA) was determined. Sorption of PA by a carboxylic ion exchanger within a wide range of pH was studied. The valu

7-Aminodesacetoxycephalosporanic acid (7-ADCA) of 99 per cent purity was prepared by enzymatic hydrolysis of 7-phenylacetamidodesacetoxycephalosporanic acid. Its isoelecti point was determined by the electrophoretic method. Potentiometric titration o

The physico-chemical properties of penicillinamidase (PA) immobilized in polyacrylamide gel (IPA) were investigated. It was shown that simple incorporation of PA into polyacrylamide gel was not effective because of gradual washing out of the enzyme.
