The 5-enolpyruvylshikimate-3-phosphate synthase catalyses the sixth step of the shikimate pathway that is responsible for synthesizing aromatic compounds and is absent in mammals, which makes it a potential target for drugs development against microbial diseases. Here, we report the phosphate binding effects at the structure of the 5-enolpyruvylshikimate-3-phosphate synthase from Mycobacterium ...

Excised petiolar vascular bundles and excised phloem tissues have been shown to take up phosphate, sulfate and sucrose by a true accumulation process and against high concentration ratios. Phosphate was accumulated principally as inorganic phosphate, and sucrose principally as sucrose. The rates of accumulation of the 3 solutes into the phloem-containing tissues were from 4 to 35 times higher t...

 This research investigate clayey, lateritic and sandy soils have been selected from agricultural lands in the South-Eastern Nigeria, for their phosphate sorption characteristics using column experiments, in order ascertain the movement of phosphate in the soils. The soil samples were equilibrated in 25ml of 0.01M CaCl2  containing different concentrations of P as KH2PO4 to produce initial conc...

The use of phosphate-based enemas as a laxative is still standard practice in clinical medicine. Absorption of phosphate with consecutive hyperphosphataemia and hypocalcaemia is a serious adverse event which is especially dangerous in patients with renal insufficiency and impaired bowel movement. Despite several reports including cases of death, the seriousness of this situation appears to be u...

phosphorus solubilizing microorganisms are capable of transforming insoluble phosphorus (p) forms to soluble and bioavailable p. the aim of the present study was to isolate p solubilizing bacteria from forest soils around the rock phosphate (rp) mine of koh-e-sepidlar in kohgiluyeh and boyer ahmad province and evaluate their ability in sperber culture medium and wheat straw medium in the presen...

Phosphate can distribute in the cell wall space, but is not bound to an appreciable extent at the cell surface in non-metabolizing yeast. During metabolism of sugars, phosphate is actively transported into the yeast cell by a mechanism specifically involving glycolysis reactions. The movement of phosphate is in the inward direction only (no appreciable efflux), and it can proceed against a conc...

phosphorus (p) is one of the most vital elements for all living organisms which acts as aconstituent of essential biomolecules such as nucleic acids, phospholipids, and phosphosugars,and as a major contributor to almost all metabolic reactions including photosynthesis,respiration, and energy delivery. it is one of the most needed nutrients for plant growth anddevelopment. despite high levels of...

objective: basic fibroblast growth factor (bfgf) is a cytokine involved in angiogenesis, tissue remodeling and stimulation of osteoblasts and osteoclasts. the present study assesses the effects of a local injection of bfgf on the rate of orthodontic tooth movement. materials and methods: in this laboratory animal study, we randomly divided 50 rats into 5 groups of 10 rats each. rats received 0....

The electroplates of the electric organ of Torpedo are embryonically derived from striated muscle fibres which lose their ability to contract and develop greatly expanded end-plate surfaces (cf. Rosenberg, 1928). From consideration of the thermodynamics of the Torpedo organ discharge, Bernstein (1912) concluded that the electric energy of the discharge was derived from a difference between the ...
