Erythrobacter sp. JK5, a marine heterotrophic bacterium, was isolated from marine sediment in Jeju island, the Republic of Korea. Here, we report information on the complete genome of strain JK5, including a putative capability for photosynthesis. The genome of JK5 consisted of 3.34 Mbp with 64.2% G + C content, and contained 3210 protein-coding sequences and three rRNA genes. Genomic analysis revealed that strain JK5 might be grown under oxic, microoxic, or anoxic conditions using two types of terminal oxidase (high and low oxygen affinity) or nitrate reductase. The types IV and VI secretion systems presented in strain JK5 genome might reveal a survival advantage against their ecological competitors in the marine environment.
海洋异养菌 Erythrobacter sp. JK5 从韩国济州岛海洋沉积物中分离得到。本研究报告了该菌株的全基因组信息，包括其潜在的光合作用能力。JK5 基因组大小为 3.34 Mbp，G+C 含量为 64.2%，包含 3210 个蛋白编码序列和 3 个 rRNA 基因。基因组分析表明，JK5 菌株可能在好氧、微氧或缺氧条件下生长，使用两种末端氧化酶（高和低氧亲和力）或硝酸盐还原酶。JK5 基因组中存在的 IV 型和 VI 型分泌系统可能揭示了其在海洋环境中相对于生态竞争者的生存优势。
