Gewinnung und Charakterisierung von Prolidase aus Escherichia coli B, II. Charakterisierung, Reinigung und Trägerfixierung des Enzyms

Abstract: Prolidase, a specific exopeptidase, is isolated from Escherichia coli B. The enzyme being present in the raw extract is purified and enriched by fractionated ammonium sulfate precipitation, ion exchange chromatography on DEAE‐Sephadex A 50 as well as by gel filtration on Sepharose 4 B. Total yield of prolidase amounts to 19% with a 67fold enrichmentSubstrate specifity of the enzyme mainly corresponds to that of the animal prolidase. It is able to hydrolize the imido linkage at the N‐terminal end of prolin in t… Show more
