Abstract
We report a first detailed bacterial inventory from vertical profiles of 60 sampling stations distributed along the salinity gradient of the Baltic Sea, one of world's largest brackish water environments, generated using 454 pyrosequencing of partial (400 bp) 16S rRNA genes. Within the salinity gr...

Abstract
We identify a previously unknown target of POA as the ribosomal protein S1 (RpsA), a vital protein involved in protein translation and the ribosome-sparing process of trans-translation. Three PZA-resistant clinical isolates without pncA mutation harbored RpsA mutations. RpsA overexpression conferred...

Biochemistry (Washington) (50)37 2011
Abstract
We benchmark the method using six molecules for which crystallographic data are available: tRNA(phe) and 5S rRNA from Escherichia coli, the P4-P6 domain of the Tetrahymena group I ribozyme, and ligand-bound domains from riboswitches for adenine, cyclic di-GMP, and glycine. SHAPE-directed modeling of...

Cell Host & Microbe (10)2 2011
Abstract
We used massively parallel cDNA sequencing (RNA-seq) techniques to quantitatively catalog the transcriptome of the cholera pathogen, Vibrio cholerae, derived from two animal models of infection. Transcripts elevated in infected rabbits and mice relative to laboratory media derive from the major know...

Abstract
We show using a kinetic model that Hfq can efficiently and robustly achieve this difficult task by minimizing the sequestration of sRNAs and target mRNAs in Hfq complexes. This sequestration can be reduced by two non-mutually exclusive kinetic mechanisms. The first mechanism involves heterotropic co...

ISME Journal (5)7 2011
Abstract
We explored the interactions of two spirochetes previously isolated from the very same termite species. As hydrogen (H(2)) is the central free intermediate in termite-gut lignocellulose digestion, we focused on interactions between two closely related termite-gut spirochetes possessing complementary...

Abstract
We performed high throughput sequencing of cDNA generated from sRNA transcripts isolated from a strain ectopically expressing ToxT, the major transcriptional regulator within the virulence gene regulon. We compared this data set with ToxT binding sites determined by pulldown and deep sequencing to i...

Abstract
We identified clinical isolates of Nocardia species by genetic methods and analyzed clinical features of nocardiosis. Nine clinical isolates were obtained in Kyushu University Hospital from 2005 to 2008. Six different Nocardia species were identified by 16Sr RNA: Nocardiafarcinia (n=2), Nocardia bra...

Abstract
We aimed to identify novel sRNAs and sORFs in Shigella, the principal etiologic agents of bacillary dysentery.
We identified 64 sRNAs in Shigella, which were experimentally validated in other bacteria based on sequence conservation. We employed computer-based and tiling array-based m...

Abstract
We do not know if the same phylotypes exist in all locations or if they exhibit genetic isolation by distance patterns. To examine their biogeographic distribution, we analyzed all available, long-read 16S rRNA gene sequences of Polaromonas phylotypes from glacial and periglacial environments across...

Abstract
Mortality in sepsis remains high and efforts to modulate the inflammatory response so far mostly failed to improve survival. The human chorionic gonadotropin-related tetrapeptide LQGV was recently shown to exert anti-inflammatory activity. The aim of this study was to assess the effect of LQGV on ce...

We show that the Streptococcus thermophilus CRISPR1/Cas system can also naturally acquire spacers from a self-replicating plasmid containing an antibiotic-resistance gene, leading to plasmid loss. Acquired spacers that match antibiotic-resistance genes provide a novel means to naturally select bacte...

Abstract
Ribosomes are self-assembling macromolecular machines that translate DNA into proteins, and an understanding of ribosome biogenesis is central to cellular physiology. Previous studies on the Escherichia coli 30S subunit suggest that ribosome assembly occurs via multiple parallel pathways rather than...

Nontuberculous mycobacteria were identified from 45891 samples of 19553 patients with a prediagnosis of pulmonary tuberculosis between November 2004 and January 2009. Among 10041 (21.9%) culture positive samples, 208 (2.1%) pulmonary samples recovered from 77 individual patients were differentiated...

Pathogenicity tests demonstrated that 13 out of 31 isolates were pathogenic, including 8 strains of V splendidus, 3 strains of Shewanella sp. and 2 strains of Pseudoalteromonas tetraodonis. The pathogenic V splendidus showed the highest frequency of appearance. Median lethal dose (LD50) v...

Abstract
Three types of nuruk were made from rice, wheat, and a rice-glasswort (6:4) mixture. Nuruk, makgeolli, and vinegar were manufactured with rice nuruk (RN), wheat nuruk (WN), and rice-glasswort nuruk (RGN). The saccharifying activity and ethanol productivity of nuruk, polyphenol content in makgeolli,...

Abstract
We performed Brownian dynamics simulations of the R.P(c) --> R.P(o) transition. In the fast trajectories, unwinding of the promoter DNA begins by local melting around the -10 element, which is followed by sequential unzipping of DNA till the +2 site. The R.P(c) --> R.P(o) transition occurs in three...

Abstract
We determined that the transcription of the auxiliary, antibiotic-resistant tryptophanyl-tRNA synthetase gene (trpRS1) in Streptomyces coelicolor is regulated by a ribosome-mediated attenuator in the 5' leader of its mRNA region. This regulatory element controls gene transcription in response to the...

Pantoea stewartii SW2 contains 13 plasmids. One of these plasmids, pSW200, has a replicon that resembles that of ColE1. This study demonstrates that pSW200 contains a 9-bp UP element, 5'-AAGATCTTC, which is located immediately upstream of the -35 box in the RNAII promoter. A transcriptional fusion s...

Little is known about the regulation of nitrogenase genes in cyanobacteria.

The results of feeding experiments with (13)C-labeled compounds indicated that...

Abstract
Aminoacyl-tRNA (aa-tRNA), in a ternary complex with elongation factor-Tu and GTP, enters the aminoacyl (A) site of the ribosome via a multi-step, mRNA codon-dependent mechanism. This process gives rise to the preferential selection of cognate aa-tRNAs for each mRNA codon and, consequently, the fidel...
