Response of Shewanella oneidensis wild type and arcA mutant strains to H2O2

ABSTRACT: We undertook a transcriptional profiling to identify genes coping with H2O2-induced oxidative stress in S. oneidensis. The data revealed that the well conserved scavenging genes such as as ahpCF, katB, and katG formed the first line of defense while iron-sulfur protecting proteins may not play a significant role.

Response of Shewanella oneidensis wild type and arcA mutant strains to H2O2

Project description:We undertook a transcriptional profiling to identify genes coping with H2O2-induced oxidative stress in S. oneidensis. The data revealed that the well conserved scavenging genes such as as ahpCF, katB, and katG formed the first line of defense while iron-sulfur protecting proteins may not play a significant role. Experimental cells collected 5 min after H2O2 treatment; Control cells collected just before H2O2 treatment. In total, 8 samples were studied (4 for wild type and 4 for arcA mutant, 4 replicates).

Genomic Array Footprinting of Shewanella oneidensis grown under aerobic conditions

Project description:We undertook a genomic array footprinting to identify genes important for aerobic growth of S. oneidensis. The data revealed that removal of 96 genes resulted in significant impacts on aerobic growth. Experimental cells collected 5 days after competition started; Control cells collected 1 day after competition started. In total, 6 samples were studied (3 for 5 days and 3 for 1 day, 3 replicates).

Quantitative proteome of Shewanella oneidensis MR-1

Project description:We investigated the anode-specific responses of Shewanella oneidensis MR-1, an exoelectroactive ammaproteobacterium, using for the first time iTRAQ and 2D-LC MS/MS driven membrane proteomics to compare protein abundances in S. oneidensis when generating power in MFCs, and growing in a continuous culture.

Transcriptional targets of Shewanella oneidensis HnoC (SO_2540)

Project description:To identify the transcriptional targets of the DNA-binding response regulator HnoC (SO_2540), mRNA transcript levels in Shewanella oneidensis were measured using whole genome microarray analysis. Transcript levels were compared between WT Shewanella oneidensis and a hnoC deletion strain. Transcript levels of a WT and hnoC deletion strain were measured after 15 hrs growth, 4 independent replicates were performed for each strain

Shewanella oneidensis arcA Mutation Impairs Aerobic Growth Mainly by Compromising Translation.

Project description:Arc (anoxic redox control), one of the most intensely investigated two-component regulatory systems in γ-proteobacteria, plays a major role in mediating the metabolic transition from aerobiosis to anaerobiosis. In Shewanella oneidensis, a research model for respiratory versatility, Arc is crucial for aerobic growth. However, how this occurs remains largely unknown. In this study, we demonstrated that the loss of the response regulator ArcA distorts the correlation between transcription and translation by inhibiting the ribosome biosynthesis. This effect largely underlies the growth defect because it concurs with the effect of chloramphenicol, which impairs translation. Reduced transcription of ArcA-dependent ribosomal protein S1 appears to have a significant impact on ribosome assembly. We further show that the lowered translation efficiency is not accountable for the envelope defect, another major defect resulting from the ArcA loss. Overall, our results suggest that although the arcA mutation impairs growth through multi-fold complex impacts in physiology, the reduced translation efficacy appears to be a major cause for the phenotype, demonstrating that Arc is a primary system that coordinates proteomic resources with metabolism in S. oneidensis.
