Abstract
Kitasatospora cheerisanensis KCTC 2395, producing bafilomycin antibiotics belonging to plecomacrolide group, was isolated from a soil sample at Mt. Jiri, Korea. The draft genome sequence contains 8.04 Mb with 73.6% G+C content and 7,810 open reading frames. All the genes for aerial mycelium and spore formations were confirmed in this draft genome. In phylogenetic analysis of MurE proteins (UDP-N-acetylmuramyl-L-alanyl-D-glutamate:DAP ligase) in a conserved dcw (division of cell wall) locus, MurE proteins of Kitasatospora species were placed in a separate clade between MurEs of Streptomyces species incorporating LL-diaminopimelic acid (DAP) and MurEs of Saccharopolyspora erythraea as well as Mycobacterium tuberculosis ligating meso-DAP. From this finding, it was assumed that Kitasatospora MurEs exhibit the substrate specificity for both LL-DAP and meso-DAP. The bafilomycin biosynthetic gene cluster was located in the left subtelomeric region. In 71.3 kb-long gene cluster, 17 genes probably involved in the biosynthesis of bafilomycin derivatives were deduced, including 5 polyketide synthase (PKS) genes comprised of 12 PKS modules.
