Native sodium and potassium adenosine triphosphatase from guinea pig kidney accepted a phosphate group from radioactive inorganic phosphate to form an acyl phosphate bond at the active site in the presence or absence of sodium ion. Magnesium ion was always required. In the presence of sodium ion and absence of adenosine triphosphate, there was no phosphorylation by inorganic phosphate. Addition...

The high resolution X-ray structures of 38 proteins that bind phosphate containing groups and 36 proteins binding sulphate ions were analysed to characterise the structural features of anion binding sites in proteins. 34 of the 66 phosphates found were in close proximity to the amino terminus of an alpha-helix. 27% of phosphate groups bind to only one amino acid, but there is a wide distributio...

Native solium and potassium adenosine triphosphatase from guinea pig kidney accepted a phosphate group from radioactive inorganic phosphate to form an acyl phosphate bond at the active site in the presence or absence of sodium ion. Magnesium ion was always required. In the presence of sodium ion and absence of adenosine triphosphate, there was no phosphorylation by inorganic phosphate. Addition...

Notions of quasi-classical Lie-super algebra as well as Lie-super triple systems have been given and studied with some examples. Its application to Yang-Baxter equation has also been given. 1991 Mathematics Subject Classification Primary 17A40, 17B60

The apparent molar volumes (?v) and viscosity B coefficients (Jones Dole)for Magnesium sulphate, Aluminium ammonium sulphate Potassium aluminium in aqueous Dimethylformamide (DMF) Dimethyl sulphoxide (DMSO) were evaluated from density (?) (?) at various temperatures as 308.15, 313.15, 318.15 323.15K with help of bicapillary pycnometer Ubbelohde viscometer instruments respectively. densitydata f...

This experimental study was carried out to investigate the effect of medical grade calcium sulphate and β-tricalcium phosphate/ hydroxyapatite on new bone formation. Additionally, the study compared these materials for infection, resorption, biocompatibility, immune reaction, fi brotic encapsulation, foreign body reaction and physical attachment. Forty, fi ve-month-old female Wistar Albino rats...
