phenylalanine dehydrogenase (phedh; ec 1.4.1.20) is an important enzyme of amino acid dehydrogenases family that increasingly used as a valuable biocatalyst in neonatal screening kits and synthesis of l-phenylalanine. the goal of this literature was to find a suitable purification method for recombinant bacillus badius phedh by practical comparison between chromatographic and polyvinyl pyrrolid...

Sulphate ions have been known for some years to enhance the activity of hepatic glycogen phosphorylase b in vitro. Here we report that intravenous injections of 4.92 mmol of Na2SO4/kg body wt. to rats induced marked hepatic glycogenolysis in vivo, accompanied by polyuria, glycosuria and a mild hyperglycaemia. These effects were observed both in normal (Wistar) rats and in gsd/gsd rats that lack...

In five cultivated rice varieties e.g., Nonabokra, PNR 381, Taipei 309, Koshika and TKM 11 the response in the initiation of callus and its size varied greatly among varieties, salt concentrations (NaCl and Na2SO4) and their interaction. Better regeneration ability of Nonabokra, Koshika and TKM 11 was found to be correlated to small size callus with a high concentration of Na2SO4. The regenerat...

Current research on effect of increasing concentrations (0 (control), 100, 200, 300, 400 and 500 mM) of different salts including NaCl and Na2SO4 on germination and initial growth phase of Halostachys caspica were studied. The experimental design was completely randomized design with three replications. Characters of percentage, speed and index of germination, seed healthy index, radicle, plumu...

Partition behavior of adenosine and guanine mononucleotides was examined in aqueous dextran-polyethylene glycol (PEG) and PEG-sodium sulfate two-phase systems. The partition coefficients for each series of mononucleotides were analyzed as a functions of the number of phosphate groups and found to be dependent on the nature of nucleic base and on the type of ATPS utilized. It was concluded that ...

current research on effect of increasing concentrations (0 (control), 100, 200, 300, 400 and 500 mm) of different salts including nacl and na2so4 on germination and initial growth phase of halostachys caspica were studied. the experimental design was completely randomized design with three replications. characters of percentage, speed and index of germination, seed healthy index, radicle, plumu...

Studies on precipitation and turbidimetric methods for fibrinogen determination employing Na2SO3, Na2SO4, (NH4) 2S04 and a mixture of phosphate salts are presented. Optimal reaction conditions for these technics have been verified. The amounts of plasma fibrinogen precipitated by the sulfite and phosphate methods are in closer agreement than either are with values obtained by the (NH4)2S04 and ...
