Abstract
본 발명에 따른 신규 베타-갈락토시다아제를 사용하면, 갈락토올리고당을 효율적으로 대량 생산할 수 있다.
Description
도 2는 재조합 베타-갈락토시다제 유전자가 형질전환된 대장균 DH5α/pACE-BgaI.New에서 생산된 재조합 베타-갈락토시다제의 단백질 발현 양상을 SDS-PAGE로 확인한 결과이다 (M: 단백질 사이즈 마커, 1: DH5α /None, 2: DH5α/pACE-BgaI.New, 화살표: 베타-갈락토시다제).
도 3은 형질전환된 대장균 DH5α/pACE-BgaI.New에서 생산된 재조합 베타-갈락토시다제의 최적 온도를 나타낸 것이다.
