Properties and Regulation of Aspartate Kinase from Barley Seedlings (Hordeum vulgare L.).
Aspartate kinase (EC 2.7.2.4) has been purified 8-fold and characterized from germinating barley (Hordeum vulgare) seedlings. The enzyme is inhibited 50% by 0.7 mm l-lysine and almost completely at 5 mm. l-Methionine does not affect the enzyme on its own, but at low concentrations (0.1-1 mm) increases the inhibition in the presence of lysine, indicating that the two amino acids act as cooperati...

متن کاملPhosphorus acquisition by barley (Hordeum vulgare L.) at suboptimal soil temperature
We studied the effects of soil temperature (8 °C and 15 °C) on barley growth, barley phosphorus (P) uptake and soil P solubility. Barley was grown in a pot experiment in two soils with different P fertilization histories for 22 years. The availability of P was estimated by using 33P-labeled fertilizer and calculating L-values. After cultivation for 22 years at ambient soil temperature without P...
متن کاملHordeum vulgare Seedlings Amine Oxidase: Purification and Properties.
Although no amine oxidase could be detected in crude extracts, the enzyme has been purified to apparent homogeneity from Hordeum vulgare seedlings using ammonium sulfate precipitation and chromatography on DEAE cellulose, Hydroxylapatite, and Sephadex G200 columns. Gel filtration experiments indicate a molecular weight of about 150,000. The pH optimum of the enzyme was found to be 7.5 in potass...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
