  • Bactobolin analog and synthesis method thereof
    Patent number: 8222434
    Abstract: The present inventions are directed to a novel bactobolin analog bactobolin D. The present inventions also are directed to a method of producing a composition comprising at least one bactobolin analog using a bacteria strain comprising a bacterial cell comprising the biosynthetic locus of the bactobolin analog in Burkholderia thailandensis (bta cluster) or a homolog structure (at least 95% sequence identity) thereof, and further isolation and purification of the bactobolin analog. For example, the bacterial strain can be a wild type bacterial strain such as a Burkholderia strain comprising a bta cluster (e.g. Burkholderia thailandensis (e.g. E264, Bt4, and TXDOH) and Burkholderia pseudomallei (e.g. K96243, 1106a, and 1106b).
