Phosphate Starvation Inducible Metabolism in Lycopersicon esculentum: II. Characterization of the Phosphate Starvation Inducible-Excreted Acid Phosphatase.
Three-day-old suspension cultured cells of Lycopersicon esculentum transferred to a Pi-depleted medium had 2.7 times the excreted acid phosphatase (Apase) activity of cells transferred to a Pi-sufficient medium. Cell growth during this time period was identical for the two treatments. Excreted Apase activity was resolved into two fractions on a Sephadex G-150 column. Most of the phosphate starv...
متن کاملPhosphate starvation promotes swarming motility and cytotoxicity of Pseudomonas aeruginosa.
We investigated the transcriptional responses of Pseudomonas aeruginosa under phosphate-deficient (0.2 mM) conditions compared to phosphate sufficiency (1 mM). This elicited enormous transcriptional changes in genes related to phosphate acquisition, quorum sensing, chemotaxis, toxin secretion, and regulation. This dysregulation also led to increased virulence-associated phenotypes, including sw...
متن کاملRegulation of components of the Pseudomonas aeruginosa phosphate-starvation-inducible regulon in Escherichia coli.
Plasmids pPBP and pRS-XP containing the cloned genes for the Pseudomonas aeruginosa phosphate-starvation-inducible periplasmic phosphate-binding protein and outer membrane porin P (oprP), respectively, were introduced into various Escherichia coli Pho-regulon regulatory mutants. Using Western immunoblots and specific antisera, the production of both gene products was observed to be under the co...
متن کاملExpression in Caulobacter crescentus of the phosphate-starvation-inducible porin OprP of Pseudomonas aeruginosa.
The gene for the phosphate-starvation-inducible outer membrane protein OprP, of Pseudomonas aeruginosa was introduced into Caulobacter crescentus CB2A on a plasmid vector. As is the case in P. aeruginosa and Escherichia coli the oprP gene was inducible under conditions of limiting phosphate in C. crescentus. However, the maximal medium concentration of phosphate which still permitted induction ...
متن کاملPhosphate Starvation Inducible ;Bypasses' of Adenylate and Phosphate Dependent Glycolytic Enzymes in Brassica nigra Suspension Cells.
When Brassica nigra leaf petiole suspension cells were subjected to 7 days of inorganic phosphate (Pi) starvation the extractable activity of: (a) pyrophosphate:fructose 6-phosphate 1-phosphotransferase, nonphosphorylating NADP-glyceraldehyde 3-phosphate dehydrogenase, phosphoenolpyruvate phosphatase, and phosphoenolpyruvate carboxylase increased at least fivefold, (b) phosphorylating NAD-glyce...
