Abstract:
본 발명은 서열번호 2에 기재된 아미노산 서열을 코딩하는 에스테라아제(ESTL120P) 유전자 내에 다중 클로닝 위치(multiple cloning site, MCS)가 도입되어 있는 재조합 폴리뉴클레오티드에 관한 것으로, 상기 재조합 폴리뉴클레오티드를 인디케이터(indicator)로서 사용하여 외래 유전자를 포함하는 클론을 선별하는 단계를 포함하는 재조합 유전자 클로닝 벡터의 제조방법은 기존의 인디케이터(indicator)들 보다 저가의 기질을 이용하며 짧은 배양시간을 통해 빠르고 정확하게 재조합 균체의 선별이 가능하며, PCR 증폭 산물을 직접 클로닝할 수 있는 TA 클로닝 벡터와의 접목을 통해 상업적으로 판매되는 기존의 클로닝 벡터내의 인디케이터(indicator)들을 대체 할 수 있을 것으로 기대된다. 인디케이터, 에스테라아제, 다중 클로닝, 폴리뉴클레오티드
Abstract:
PURPOSE: A novel xylitol dehydrogenase and a method for preparing xylitol using the same are provided to reuse NADP+ by reducing to NADPH and to produce xylitol with high yield. CONSTITUTION: A xylitol dehydrogenase is used together with NADP+ having an amino acid of sequence number 1. A polynucleotide encoding the xylitol dehydrogenase has a base sequence of sequence number 2. A vector comprises a promoter and the polynucleotide which is operatively linked with the promoter. A microorganism which expresses the xylitol dehydrogenase is transformed by the vector. The microorganism is Candida tropicalis ARSdR-16(KCTC-11568BP).

PURPOSE: An esterase gene and recombinant polynucleotide are provided to replace an indicator in a conventional cloning vector through combining with TA cloning vector. CONSTITUTION: An esterase gene encodes an amino acid sequence of sequence number 2. The esterase gene comprises a sequence of sequence number 1. A recombinant polynucleotide has multiple cloning site in the esterase gene. The multiple cloning site is introduced one of sited from between 216th and 217th, 281th and 282th, and 306th and 307th in sequence number 2. The multi cloning site comprises a sequence of sequence number 12. The recombinant vector is TA cloning vector.
Abstract:
The present invention relates to a novel red fluorescent protein variant, as a new reporter and detection probe, of which stable but quick and strong fluorescence is induced, and more specifically, to a red fluorescent protein which is formed by adding amino acid Ser, Lys or Pro-Ile-Val at the N-end of a wild-type DsRed2 gene.
