Zinc-Dependent Transcriptional Regulation in Paracoccus denitrificans
Zinc homeostasis is critical for bacterial survival and is mediated largely at the transcriptional level by the regulation of zinc uptake and efflux genes. Here we use RNA-seq to assess transcriptional changes as a result of zinc limitation in the denitrifying bacterium Paracoccus denitrificans. The results identify the differential expression of 147 genes, most of which were upregulated in zin...
متن کاملParacoccus denitrificans cytochrome c1 gene replacement mutants.
We describe the construction and characterization of gene replacement mutants for the respiratory chain component cytochrome c1 in the bacterium Paracoccus denitrificans. Its structural gene (fbcC) was inactivated by insertion of the kanamycin resistance gene, introduced into a suicide vector, and conjugated into Paracoccus; chromosomal mutants obtained by homologous recombination were selected...
متن کاملDetermination of the Paracoccus denitrificans SOS box.
By gel retardation experiments with crude cell extracts of Paracoccus denitrificans it was demonstrated that a protein specifically binds to the promoter of the P. denitrificans recA gene. PCR mutagenesis of the recA promoter showed that the GAACN7GAAC motif is required for the formation of the DNA-protein complex. This protein also binds to the GTTCN7GTTC motif, which is present in the promote...
متن کاملThe terminal oxidases of Paracoccus denitrificans.
Three distinct types of terminal oxidases participate in the aerobic respiratory pathways of Paracoccus denitrificans. Two alternative genes encoding sub unit I of the aa3 -type cytochrome c oxidase have been isolated before, namely ctaDI and ctaDII. Each of these genes can be expressed separately to complement a double mutant (ActaDI, ActaDII), indicating that they are isoforms of subunit I of...
متن کاملTransfer of Thiosphaera pantotropha to Paracoccus denitrificans.
Comparative sequence analysis of in vitro-amplified 16S rRNA genes of Thiosphaera pantotropha GB17T (T = type strain) and Paracoccus denitrificans LMG 4218T revealed identical 16S rRNA primary structures for the two organisms. The level of overall DNA similarity of Thiosphaera pantotropha GB17T and P. denitrificans DSM 65T is 85%, as determined by quantitative DNA-DNA hybridization. Therefore, ...
