  • Publication number: 20080293060
    Abstract: 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.

  • Patent number: 7033818
    Abstract: Regions of sequence identity are recurrent in some modular polyketide synthase (PKS) gene clusters. Such sequences are potentially detrimental to the stability of PKS gene clusters and expression plasmids for the genes in the gene cluster. PKS gene and gene cluster stability can be improved, and reproducible polyketide titers can be obtained using those genes and gene clusters when the regions of sequence identity are reduced or eliminated by replacing one or more identical or homologous segments with non-homologous segments that encode the same or a substantially similar amino acid sequence.
