Complete genome sequence of marine photoheterotophic bacterium Erythrobacter sp. JK5.

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.
