${it Deinococcus grandis}$ was isolated as a gram-negative, red-pigmented, radioresistant, rod-shaped bacterium from freshwater fish. The draft genome sequence of ${it D. grandis}$ ATCC 43672 was 4,092,497 bp, with an average G+C content of 67.5% and comprised of 4 circular contigs and 3 linear contigs that was deposited at DDBJ/EMBL/Genbank under the accession number BCMS00000000. The draft genome sequence indicates that ${it D. grandis}$ possesses a DNA damage response regulator (encoded by ${it pprI}$ homolog) and radiation-desiccation response regulons (${it recA}$, ${it ddrA}$, ${it ddrO}$, ${it pprA}$ and ${it gyrA}$ homologs etc.), which are involved in the unique radiation-desiccation response system in ${it D. radiodurans}$. As it is for ${it D. radiodurans}$, ${it D. grandis}$ seems to employ the same radioresistant mechanisms. In future, the draft genome sequence of ${it D. grandis}$ will be useful for elucidating the common principles of the radioresistance based on the extremely efficient DNA repair mechanisms in Deinococcus species by the comparative analysis of genomic sequences.

Draft genome sequence of ${it Methylobacterium}$ sp. ME121, isolated from soil as a mixed single colony with ${it Kaistia}$ sp. 32K

${it Methylobacterium}$ sp. ME121 was isolated from soil as a mixed single colony with ${it Kaistia}$ sp. 32K during our screening of L-glucose-utilizing microorganisms, and its growth was enhanced by coculture. It was expected that genomic analysis of this bacterium would provide novel information on coculture-dependent growth enhancement. The genomic information of symbiotic bacteria could be of use for studying the molecular mechanisms underlying microbial symbiosis. The draft genome sequence of ${it Methylobacterium}$sp. ME121 is 7,096,979 bp in total length and comprises 197 large contigs ($$>$$ 500 bp) that was deposited at DDBJ/EMBL/GenBank under the accession number BBUX00000000. The draft genome sequence shows that ${it Methylobacterium}$ sp. ME121 has some genes that encode putative methanol/ethanol family PQQ-dependent dehydrogenases involved in methylotrophy. Some unknown factor provided by the coculture may contribute to increase the growth of ${it Methylobacterium}$ sp. ME121.

The alkaliphilic bacterium ${it Bacillus alcalophilus}$ AV1934, isolated from human feces, recent has indicated novel potassium ion coupling to motility in this extremophile. We report draft sequences that will facilitate an examination of whether that coupling is part of a larger cycle of potassium ion-coupled transporters. This draft genome has 4,095 predicted genes and 4,063 predicted proteins. The whole-genome shotgun project has been deposited in Genbank under the accession no. ALPT02000000. In addition to the ${it mot}$ genes encoding the MotPS channel that uses either potassium or sodium coupling, two loci encoding multisubunit Mrp-type antiporters, were found. The ${it B. alcalophilus}$ AV1934 genome reveals no tripartite ATP-independent (TRAP-T family) uptake systems,a major sodium-coupled complement in the other two alkaliphiles. The ${it B. alcalophilus}$ AV1934 genomic data will enable us to test the hypothesis of a major role of potassium in ion coupling in this extremophile.

Draft genome sequence of calcium-dependent ${it Paenibacillus}$ sp. strain TCA20, isolated from a hot spring containing a high concentration of calcium ions

藤浪 俊*; 武田 喜代子*; 小野寺 威文*; 佐藤 勝也; 佐野 元彦*; 高橋 優嘉*; 鳴海 一成*; 伊藤 政博*

Genome Announcements (Internet), 2(5), p.e00866-14_1 - e00866-14_2, 2014/09

Calcium-dependent ${it Paenibacillus}$ sp. strain TCA20 was isolated from a water sample of a hot spring containing a high concentration of calcium ions. Here, we report the draft genome sequence of this bacterium, which may be the basis for the research of calcium ion homeostasis. The draft genome sequence of ${it Paenibacillus}$ sp. strain TCA20 totals 5,631,463 bp in length and is composed of 33 large contigs ($$>$$ 500 bp) that was deposited at DDBJ/EMBL/Genbank under the accession no. BBIW00000000. The annotation of the draft genome sequence shows that ${it Paenibacillus}$ sp. strain TCA20 has a calcium-specific calcium/proton antiporter, ChaA, and a P-type calcium-transporting ATPase, YloB, was identified as calcium transporters. These transporters may also be important for the growth of ${it Paenibacillus}$ sp. strain TCA20 under the high concentration of calcium ions.

Draft genome sequence of potassium-dependent alkaliphilic ${it Bacillus}$ sp. strain TS-2, isolated from a jumping spider

藤浪 俊*; 武田 喜代子*; 小野寺 威文*; 佐藤 勝也; 佐野 元彦*; 鳴海 一成*; 伊藤 政博*

Genome Announcements (Internet), 2(3), p.e00458-14_1 - e00458-14_2, 2014/05

The potassium-dependent alkaliphilic ${it Bacillus}$ sp. strain TS-2 was isolated from the mashed extract of a jumping spider, and its draft genome sequence was obtained. Comparative genomic analysis with a previously sequenced sodium-dependent alkaliphilic ${it Bacillus}$ species may reveal potassium-dependent alkaline adaptation mechanisms. The draft genome sequence of ${it Bacillus}$ sp. strain TS-2 was 4,360,646 bp in total length, comprised 58 large contigs ($$>$$ 500 bp) that was deposited at DDBJ/EMBL/Genbank under the accession number BAWL00000000. In the draft genome sequence of ${it Bacillus}$ sp. strain TS-2, two sets of ${it mrp}$ genes, which encode multisubunit secondary cation/proton antiporter-3 family proteins, were annotated. The Mrp complex acts as an Na$$^{+}$$/H$$^{+}$$ antiporter in typical alkaliphilic ${it Bacillus}$ species and plays a critical role in the sodium-dependent alkaline adaptation mechanism.

Genome Announcements (Internet), 1(6), P. e01043-13, 2013/12

Alkaliphilic ${it Microbacterium}$ sp. strain TS-1, newly isolated from the jumping spider, showed Na$$^{+}$$-independent growth and motility. Here, we report the draft genome sequence of this bacterium, which may provide beneficial information for Na$$^{+}$$-independent alkaline adaptation mechanisms. The draft genome sequence of ${it Microbacterium}$ sp. strain TS-1 was 3,396,165 bp in total length and comprised 3 large contigs (2,699,404 bp, 691,278 bp, and 5,483 bp) that was deposited at DDBJ/ EMBL/GenBank under the accession number BASQ00000000. The annotation of the draft genome sequence indicated that this bacterium has 3 sets of ${it mrp}$ genes, which encode multisubunit secondary cation/proton antiporter-3 family proteins for pH homeostasis. The annotation also indicated that this bacterium has genes involved in chemotaxis/flagellar components, including one set of ${it mot}$ genes.
