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 (UDPN-
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. |
