Abstract:
The present disclosure provides methods, reagents, systems, and devices that target β lactamase as a biomarker for the sensitive and specific detection of tuberculosis-complex bacteria. Specifically, the present disclosure relates to methods and compositions for the detection of specific β-lactamase protein and nucleic acid sequences to indicate the presence of tuberculosis-complex bacteria.
Abstract:
Disclosed are transformed cells and related nucleotide and protein sequences, and fermentation compositions and methods, all of which are related to providing selective advantage in fermentation. For example, a selective advantage results from transformation of a cell with a nucleic acid that allows a transformed cell to metabolize one or more nitrogen-, phosphorous-, and/or sulfur-containing compounds that a native cell of the same species as the transformed cell cannot metabolize, and from fermentation of the transformed cell using one or more feedstocks, such as fractioned grain, which are depleted in or free of conventional nitrogen-, phosphorous-, and/or sulfur-containing compounds that a native cell of the same species as the transformed cell can metabolize. Also disclosed are methods for improved oxygen transfer in an aerobic or microaerobic fermentation.
Abstract:
본 발명은 대장균(E.coli)에서 재조합 단백질을 발현시킬 때, 외래 유전자 내의 코돈(codon)과 숙주의 호환성이 좋지 않아 발생하는 번역속도의 불안정성을 해결할 수 있는 램프 태그(ramp tag)에 관한 것이다. 본 발명은 희귀 코돈(rare codon)의 문제를 해결하는 기존의 코돈 최적화(codon optimization) 또는 코돈 탈최적화(codon deoptimization) 방법과 달리 원래의 코돈 서열을 바꾸지 않고 단지 램프 태그를 목적 유전자와 융합하거나 독립적으로 발현하도록 하여 tRNA를 재사용하게 함으로써 목적 단백질의 발현 효율을 증가시킨다. 따라서 본 발명은 DNA 서열을 인공으로 합성하는 코돈 최적화 방법에 비해 비용과 시간을 절감할 수 있는, 재조합 단백질 발현을 증가시키는 새로운 방법으로 부가가치가 높은 의약품이나 산업용 효소의 생산에 이용될 수 있을 것으로 기대된다.
