Purification, characterization, and crystallization of human pyrroline-5-carboxylate reductase.
Pyrroline-5-carboxylate reductase (P5CR) catalyzes the reduction of Delta1-pyrroline-5-carboxylate (P5C) to proline with concomitant oxidation of NAD(P)H to NAD(P)(+). The enzymatic cycle between P5C and proline is very important in many physiological and pathological processes. Human P5CR was over-expressed in Escherichia coli and purified to homogeneity by chromatography. Enzymatic assays of ...
متن کاملCrystal structure of human pyrroline-5-carboxylate reductase.
Pyrroline-5-carboxylate reductase (P5CR) is a universal housekeeping enzyme that catalyzes the reduction of Delta(1)-pyrroline-5-carboxylate (P5C) to proline using NAD(P)H as the cofactor. The enzymatic cycle between P5C and proline is very important for the regulation of amino acid metabolism, intracellular redox potential, and apoptosis. Here, we present the 2.8 Angstroms resolution structure...
متن کاملPurification to homogeneity of pyrroline-5-carboxylate reductase of barley.
An enzyme has been purified to homogeneity from barley seedlings which has ;proline dehydrogenase' and the pyrroline-5-carboxylic acid reductase activities. The purification achieved is 39,000-fold as calculated from the proline dehydrogenase activity. The subunit molecular weight of the protein is 30 kilodaltons. The native enzyme has molecular weights up to 480 kilodaltons, depending on the b...
متن کاملa case study of the two translators of the holy quran: tahereh saffarzadeh and laleh bakhtiar
بطورکلی، کتاب های مقدسی همچون قران کریم را خوانندگان میتوان مطابق با پیش زمینه های مختلفی که درند درک کنند. محقق تلاش کرده نقش پیش زمینه اجتماعی-فرهنگی را روی ایدئولوژی های مترجمین زن و در نتیجه تاثیراتش را روی خواندن و ترجمه آیات قرآن کریم بررسی کند و ببیند که آیا تفاوت های واژگانی عمده ای میان این مترجمین وجود دارد یا نه. به این منظور، ترجمه 24 آیه از آیات قرآن کریم مورد بررسی مقایسه ای قرار ...
15 صفحه اولOsmoregulation of a pyrroline-5-carboxylate reductase gene in Arabidopsis thaliana.
In Arabidopsis thaliana (L.) Heynh. proline can account for up to 20% of the free amino acid pool after salt stress. Proline accumulation occurs in plants mainly by de novo synthesis from glutamate. The last step of the proline biosynthetic pathway is catalyzed by pyrroline-5-carboxylate (P5C) reductase. A gene (AT-P5C1) encoding this enzyme in A. thaliana has been cloned and sequenced. Express...
