Genomic view of energy metabolism in Ralstonia eutropha H16.
Ralstonia eutropha is a strictly respiratory facultative lithoautotrophic beta-proteobacterium. In the absence of organic substrates, H2 and CO2 are used as sole sources of energy and carbon. In the absence of oxygen, the organism can respire by denitrification. The recent determination of the complete genome sequence of strain H16 provides the opportunity to reconcile the results of previous p...
متن کاملEssential role of the hprK gene in Ralstonia eutropha H16.
Ralstonia eutropha H16 possesses an incomplete phosphoenolpyruvate (PEP):sugar phosphotransferase system (PTS) composed of EI, HPr, EIIA(Ntr) (PtsN) and EIIA(Man) (PtsM). We could show that in vitro the incomplete PTS phosphorylation cascade is partially functional. HPr becomes phosphorylated by PEP and EI, and transfers the phosphoryl group to EIIA(Ntr), but only extremely slowly to EIIA(Man)....
متن کاملTranscriptional regulation of nitric oxide reduction in Ralstonia eutropha H16.
Nitric oxide reduction in Ralstonia eutropha H16 is catalysed by the quinol-dependent NO reductase NorB. norB and the adjacent norA form an operon that is controlled by the sigma(54)-dependent transcriptional activator NorR in response to NO. A NorR derivative containing MalE in place of the N-terminal domain binds to a 73 bp region upstream of norA that includes three copies of the putative up...
متن کاملProduction of polyhydroxyalkanoate biopolymer from vinasse using Ralstonia eutropha
Background Brazil is the world’s leading ethanol producer and exporter. Due to increasing fuel demands, ethanol production has escalated in recent years. Vinasse is generated as a byproduct of the ethanol industry and is mainly used as fertilizer. The excessive usage of vinasse in soil leads to groundwater contamination [1]. The objective of this project is to develop a fermentation process wit...
متن کاملCorrection for Brigham et al., "Whole-Genome Microarray and Gene Deletion Studies Reveal Regulation of the Polyhydroxyalkanoate Production Cycle by the Stringent Response in Ralstonia eutropha H16".
Poly(3-hydroxybutyrate) (PHB) production and mobilization in Ralstonia eutropha are well studied, but in only a few instances has PHB production been explored in relation to other cellular processes. We examined the global gene expression of wild-type R. eutropha throughout the PHB cycle: growth on fructose, PHB production using fructose following ammonium depletion, and PHB utilization in the ...
