Porphyromonas gingivalis 33277 wild-type vs Fur orthologue Har isogenic mutant ECR455

(Submitter supplied) Porphyromonas gingivalis is a major pathogen associated with the microbial biofilm-mediated disease chronic periodontitis. P. gingivalis has an obligate requirement for iron and protoporphyrin IX which it satisfies by transporting heme and iron liberated from the human host. The level of cellular iron in P. gingivalis affects the expression of a distinct iron-associated regulon of 64 genes and low iron invokes an iron sparing response. more...

Role of an extracytoplasmic function sigma factor, PGN_0319, in hemin utilization by Porphyromonas gingivalis

(Submitter supplied) Extracytoplasmic function (ECF) sigma factors are known to play an important role in the bacterial response to various environmental stresses. Porphyromonas gingivalis, a prominent etiological agent in human periodontitis, possesses six putative ECF sigma factors. So far, information is limited on an ECF sigma factor, PGN_0319. It has been recently reported that the expression of genes encoding some of the ECF sigma factors including PGN_0319 was affected by hemin availability. more...

The involvement of CdhR in Porphyromonas gingivalis during Nitric Oxide stress [RNA-seq]

(Submitter supplied) To understand the role of CdhR and its adjacent gene PG1236 in nitric oxide (NO) stress resistance, isogenic mutants P. gingivalis FLL457 (ΔPG1237::ermF), FLL458 (ΔPG1236::ermF) and FLL459 (ΔPG1236-37::ermF) were made by allelic exchange mutagenesis and their gene expression was studied under control and NO stress conditions. DNA microarray analysis of FLL457 showed that approximately 2% of the genes were up regulated and over 1% of the genes down regulated. more...

Polyphosphate affects gene expression and viability of Porphyromonas gingivalis W83

(Submitter supplied) Polyphosphate (polyP) is a ubiquitous and abundant compound found in bacteria, fungi, algae, plant, and animals. Among roles of intracellular polyP in bacteria are resistance and survival in the stationary phase of the growth against stress and stringent condition. Therefore, intracellular polyP is considered as a virulence factor of bacteria. In contrast, exogenous polyP has an antimicrobial activity against a variety of microorganisms. more...
