Regulation of uptake hydrogenase and effects of hydrogen utilization on gene expression in Rhodopseudomonas palustris

(Submitter supplied) We used transcriptome analysis to identify genes that were differentially expressed between wild-type (CGA010) and hupV mutant cells (CGA009) grown photoheterotrophically with malate under nitrogen-fixing conditions. We also compared the transcriptome of a hupS mutant with that of the wild type. Keywords: Genetic modification

Effects of the Fnr homologue AadR on global gene expression

(Submitter supplied) In order to define the AadR regulon we did transcriptome analysis of an aadR in frame-deletion mutant and compared to that of wild type. We found that AadR positively modulated expression of 43 genes, most of which are involved in degradation of aromatic acids under anaerobic conditions. It also activated expression of four genes encoding for unknown proteins and a possible DNA-binding stress protein. more...

FixK, a universal regulator of microaerobic growth, controls photosynthesis in Rhodopseudomonas palustris

(Submitter supplied) Facultative phototrophic bacteria are excellent models for analyzing the coordination of major metabolic traits including oxidative phosphorylation, photophosphorylation, carbon dioxide fixation and nitrogen fixation. In Rhodobacter sphaeroides and R. capsulatus, a two-component system called RegBA (PrrBA) controls these functions and it has been thought that this redox sensing regulatory system was essential for coordinating electron flow and could not be easily replaced in facultative phototrophs. more...

Redirection of metabolism for biological hydrogen production

(Submitter supplied) Photosynthetic microbes can produce the clean-burning fuel hydrogen using one of nature’s most plentiful resources, sunlight 1,2. Anoxygenic photosynthetic bacteria generate hydrogen and ammonia during a process known as biological nitrogen fixation. This reaction is catalyzed by the enzyme nitrogenase and consumes nitrogen gas, ATP and electrons 3. One bacterium, Rhodopseudomonas palustris, has a remarkable ability to obtain electrons from green plant-derived material 4,5 and to efficiently absorb both high and low intensity light energy to form ATP 6. more...

Functional genomic analysis of three nitrogenase isozymes in the photosynthetic bacterium Rhodopseudomonas palustris

(Submitter supplied) To address the question of how photosynthetic bacterium Rhodopseudomonas palustris differentially regulates gene expression of three nitrogenase isozymes (Mo, V, and Fe nitrogenases), we constructed Mo strain (Mo nitrogenase only strain), V strain (V nitrogenase only strain), and Fe strain (Fe nitrogenase only strain), and analyzed the whole genome transcriptome profiles of each mutant and wild-type cells grown under nitrogen-fixing conditions. more...

R.palustris: cbbT1 overexpression and cbbT2 overexpression

(Submitter supplied) Transcriptional profiling of Rhodopseudomonas palustris (R. palustris) comparing cbbT1 over-expressing strain with cbbT2 over-expressing strain. Goal was to discriminate the molecular mechanisms between transketolase I (cbbT1) and transketolase II (cbbT2). R.palustris is a purple non-sulfur anoxygenic phototrophic bacterium and transketolase (cbbT1 and cbbT2) is a key enzyme involved in the CBB cycle. more...

Expression analysis of Thermococcus onnurineus NA1 KCTC10859 and an Frh-deficient mutant, Frh overexpression mutant and TON_0282 deletion mutant in a T. onnurineus NA1 strain.

(Submitter supplied) Investigation of whole genome gene expression level changes in an Frh-deficient mutant, Frh overexpression mutant and TON_0282 deletion mutant, compared to the wild-type strain. In this study, as a first step to assess the role of the frhAGB-encoding hydrogenases and TON_0282 gene, we constructed three mutants by deleting each gene in a T. onnurineus NA1.

Identification of a p-coumarate degradation regulon in Rhodopseudomonas palustris using Xpression, an integrated tool for prokaryotic RNA-seq data processing

(Submitter supplied) High-throughput sequencing of cDNA prepared from RNA, an approach known as RNA-seq, is coming into increasing use as a method for transcriptome analysis. Despite its many advantages, widespread adoption of the technique has been hampered by a lack of easy-to-use, integrated, open source tools for analyzing the nucleotide sequence data that are generated. Here we describe Xpression, an integrated tool for processing prokaryotic RNA-seq data. more...
