Abstract
Shewanella sp. Arc9-LZ is a bacterium capable of synthesizing silver nanoparticles in darkness. It was isolated from the marine sediment from the Arctic Ocean (158°01'12"W; 84°28'38"N) collected during the 9th Chinese National Arctic Expedition in 2018. Here, we describe the complete genome of Shewanella sp. Arc9-LZ. The complete genome of Shewanella sp. Arc9-LZ is composed of a circular chromosome of 4,911,031bp with G+C content of 41.61mol%. The genome encodes 4040 protein-coding genes (CDSs), 104 tRNAs, and 35 rRNAs. The rRNAs contain 14 copies of 5S rRNA gene, 11 copies of 16S rRNA gene, and 10 copies of 23S rRNA gene. Based on the KEGG, COG, NR, Swiss-Prot, TCDB, and CAZy analysis, a total of 64 genes belonging to 9 kinds are related to the AgNPs synthesis. These genes are involeved in the synthesis of riboflavin, b-type cytochrome, c-type cytochrome, coenzyme Q, NADPH dehydrogenase, cytochrome c reductase, cytochrome c oxidase, nitroreductase, and nitrate reductase.
