    • Disclosed is a method using an alkane response element (ARE) from, e.g., Acinetobacter spp. to (i) identify and clone hydrocarbon biosynthesis genes, (ii) identify and clone hydrocarbon transporter genes (iii) identify and clone hydrocarbon response genes. Screening cells were developed that expressed a transcriptional activator, e.g., alkR, and included a reporter gene, e.g., GFP operatively linked to an ARE promoter, e.g., the alkM promoter. The cells were transformed with libraries from organisms capable of hydrocarbon biosynthesis. Transformed cells that expressed the reporter gene harbored library-derived genes involved in one or more of the above-mentioned processes; and these genes were isolated from the cells using standard molecular biology techniques. Additional systems were designed wherein screening cells also expressed a gene identified in the original screen, e.g., an additional hydrocarbon pathway gene, e.g., an enhancer.
    • 公开了一种使用来自例如不动杆菌属(Acinetobacter spp)的烷烃应答元件(ARE)的方法。 (i)识别和克隆烃类生物合成基因,(ii)鉴定和克隆烃转运蛋白基因(iii)鉴定和克隆烃类反应基因。 开发了表达转录激活物例如alkR的筛选细胞,并且包括报告基因,例如可操作地连接到ARE启动子的例如alkM启动子的GFP。 用能够进行烃生物合成的生物体的文库转化细胞。 表达报告基因的转化细胞携带参与一个或多个上述过程的文库衍生基因; 并使用标准分子生物学技术从细胞中分离出这些基因。 设计另外的系统,其中筛选细胞还表达在原始筛选中鉴定的基因,例如另外的烃途径基因,例如增强子。
