    • This invention provides compositions and methods for monitoring and regulating the production of a target product of a biochemical pathway in an organism, such as butanol. A gene encoding a light-emitting reporter molecule, such as luciferase, is operatively linked with a transcription regulatory nucleotide sequence that regulates transcription of an enzyme in the pathway that signals the rate of production of the target product, such as butanol dehyrogenase. When a microorganism is transfected with such a reporter construct and cultured, the reporter is expressed contemporaneously with the enzyme. The amount of light produced by the reporter indicates amount of enzyme being produced which, in turn, signals the amount of target product being produced. When the reporter is measured in real time, it provides information that can be used to regulate culture conditions and to optimize production of the target product.
    • 本发明提供了用于监测和调节生物体例如丁醇中生物化学途径的目标产物的产生的组合物和方法。 编码发光报道分子例如萤光素酶的基因与转录调节核苷酸序列可操作地连接,所述转录调节核苷酸序列调节信号通路中的酶转录,所述信号表示目标产物例如丁醇脱氢酶的产生速率。 当用这种报道构建体转染微生物并培养时,报道基因与酶同时表达。 报道基因产生的光量表明产生的酶的量,其反过来表示正在产生的目标产物的量。 当记者实时测量时,它提供的信息可用于调节培养条件并优化目标产品的生产。
