Abstract
The inulase(EC 3.2.1.7) was isolated from the tuber of Jerusalem artichoke by conventional purification methods including ammonium sulfate fractionation, Sephadex G-100 filtration, and DEAE-cellulose column chromatography. The enzyme was purified 6,470 fold with 42% recovery, The enzyme was consisted of a polypeptide of Mw 57,000. The optimum temperature and the optimum pH for the enzyme action was
돼지감자로부터 inulase를 분리한 다음 황산 암모늄침전, Sephadex G-100 겔 투과 및 DEAE-cellulose 크로마토그래피를 통하여 정제하여 최종적으로 회수율 42%의 6,470배 정제된 효소를 얻었다. 이 효소의 분자량은 57,000으로서 하나의 폴리펩티드로 구성되어 있었다. 이 효소의 최적 pH와 최적온도는pH5.0과
