d-Arabinose-5-phosphate and d-sedoheptulose-7-phosphate were found to be substrates, although not inducers, of the hexose phosphate transport system of Salmonella typhimurium. Transport of these two sugar phosphates by wild-type strains required preinduction of the hexose phosphate transport system. A mutant of S. typhimurium constitutive for this system also transported d-arabinose-5-phosphate...

Pengguanan pupuk hayati mikoriza dan batuan fosfat (rock phosphate) dalam memacu pertumbuhan tanaman jagung telah banyak dikembangkan. Penelitian ini bertujuan untuk meningkatkan hasil dengan mengkombinasikan antara penggunaan rock phosphate. dilakukan selama 3 bulan di Dusun Sengir, Sumberharjo, Prambanan. metode eksperimen lapangan menggunakan rancangan acak kelompok (RAK) faktorial yang terd...

Transport of phosphate across intestinal and renal epithelia is essential for normal phosphate balance, yet we know less about the mechanisms and regulation of intestinal phosphate absorption than we do about phosphate handling by the kidney. Recent studies have provided strong evidence that the sodium-phosphate cotransporter NaPi-IIb is responsible for sodium-dependent phosphate absorption by ...

Alkaline phosphatase (ALP) activity was detected using bovine serum albumin (BSA)-functionalized manganese-doped zinc sulfide (Mn–ZnS) quantum dots (QDs), and the phosphate substrate vitamin-B 6 cofactor pyridoxal 5′-phosphate (PLP).

Calcium phosphate nanoparticles are suitable as scaffolds for bone regeneration; however, few reports on available calcium phosphate-based biomaterials with an antibacterial property drug carriers. Lei Nie and colleagues developed silver-doped biphasic phosphate/alginate microclusters using the double-emulsions method. The cover image shows SEM micrograph of prepared in which spherical shape su...

this study presents a comparison between aluminum and iron plate electrodes on phosphate removal from aqueous solutions by electrocoagulation process. the effectiveness of main operational parameters such as initial ph, initial phosphate concentration and current density were examined. in addition, treated solution and sludge characteristics, energy consumption and electrode mass depletion w...

“Phosphotransferase” activity, which has been previously described (l), involves the enzymic transfer of phosphate from various aryl phosphates to particular hydroxyl compounds, apparently without the mediation of a nucleotide. It was indicated in this work that the phosphate group was transferred directly from the donor to the acceptor compound. The main basis for this belief was the observati...
