Complete genome sequence of Celeribacter marinus IMCC12053(T), the host strain of marine bacteriophage P12053L.

Isolated from coastal seawater from Yellow Sea of Korea, Celeribacter marinus IMCC12053 was used as the host bacterium for bacteriophage P12053L. Here we report the complete genome sequence of strain IMCC12053 for further study of the marine bacteriophage P12053L functional genes. Single molecule real-time technology (PacBio RSII) was used for the single circular chromosome that is 3,096,705 base pairs in length and the GC content is 56.24%. It contains 3155 ORFs with 45 tRNAs and 6 rRNAs genes. N(6)-methyladenosine patterns were also investigated for 32 unmethylated genes and intergenic regions that covered many regulators and phage genes as well as ribosomal RNA genes and tRNA genes. Cryptic N(4)-methylcytosine pattern was investigated to speculate GpC methylase activity throughout the genome. Comparative genomics with other Celeribacter genomes were carried out for polyaromatic hydrocarbon degradation, but there were no aromatic ring oxygenases in IMCC12053 when compared to Celeribacter indicus P73.
