Natrinema sp. J7-2 is an extreme haloarchaeon capable of growing on synthetic media without amino acid supplements. Here we report the complete genome sequence of Natrinema sp. J7-2 which is composed of a 3,697,626-bp chromosome and a 95,989-bp plasmid pJ7-I. This is the first complete genome sequence of a member of the genus Natrinema. We demonstrate that Natrinema sp. J7-2 can use gluconate, glycerol, or acetate as the sole carbon source and that its genome encodes complete metabolic pathways

Abstract Background In silico analysis has shown that all bacterial genomes contain a low percentage of ORFs with undetected frameshifts and in-frame stop codons. These interrupted coding sequences (ICDSs) may really be present in the organism or may result from misannotation based on sequencing errors. The reality or otherwise of these sequences has majo

The enteric pathogen Salmonella enterica is one of the leading causes of foodborne illness in the world. The species is extremely diverse, containing more than 2,500 named serovars that are designated for their unique antigen characters and pathogenicity profiles-some are known to be virulent pathogens, while others are not. Questions regarding the evolution of pathogenicity, significance of antigen characters, diversity of clustered regularly interspaced short palindromic repeat (CRISPR) loci,

Citrobacter amalonaticus Y19 (Y19) was isolated because of its ability for carbon monoxide-dependent hydrogen production (water-gas shift reaction). This paper reports the assimilation of glycerol and the production of 1,3-propanediol (1,3-PDO) by Y19. Genome sequencing revealed that Y19 contained the genes for the utilization of glycerol and 1,2-propanediol (pdu operon) along with those for the synthesis of coenzyme B12 (cob operon). On the other hand, it did not possess the genes for the ferme

In Escherichia coli, repression of the aceBAK operon is mediated by the IclR protein. We used an in vitro oligonucleotide selection technique to determine the consensus recognition sequence for MR. Mutational analysis confirmed the contribution of this sequence to repression in vivo and identified the -35 element of the promoter.

The aceBAK operon was partially induced by a multicopy plasmid which carried the promoter region of the gene which encodes its repressor, iclR. Gel shift and DNase I analyses demonstrated that IclR binds to its own promoter. Disruption of iclR increased the expression of an iclR::lacZ operon fusion. Although aceBAK and iclR are both regulated by IclR, aceBAK expression responds to the carbon source, while expression of iclR does not.

ABSTRACT We present the draft genome sequence of Pseudomonas stutzeri TS44, a moderately halotolerant, arsenite-oxidizing bacterium isolated from arsenic-contaminated soil. The genome contains genes for arsenite oxidation, arsenic resistance, and ectoine/hydroxyectoine biosynthesis. The
