Draft Genome Sequence of Roseovarius sp. A-2, an Iodide-Oxidizing Bacterium Isolated from Natural Gas Brine Water, Chiba, Japan

摘要

Roseovarius sp. A-2 is a heterotrophic iodide (I^-)-oxidizing bacterium isolated from iodide-rich natural gas brine water in Chiba, Japan. This strain oxidizes iodide to molecular iodine (I₂) by means of an extracellular multicopper oxidase. Here we report the draft genome sequence of strain A-2. The draft genome contained 46 tRNA genes, 1 copy of a 16S-23S-5S rRNA operon, and 4,514 protein coding DNA sequences, of which 1,207 (27%) were hypothetical proteins. The genome contained a gene encoding IoxA, a multicopper oxidase previously found to catalyze the oxidation of iodide in Iodidimonas sp. Q-1. This draft genome provides detailed insights into the metabolism and potential application of Roseovarius sp. A-2.
