Kinetics of copper(II) uptake by apoazurin in complexing media.
We have studied the kinetics of copper uptake by apoazurin in imidazole and 1-methylimidazole buffers in the pH range of 7-9 with mu = 0.5 M and copper(II) in large excess. The reaction has been monitored by measuring the visible absorbance and circular dichroism as a function of time. The uptake occurs in a stepwise fashion, and at least two intermediates are implicated. Overall, the rate of u...
متن کاملG protein-coupled receptor allosterism and complexing.
G protein-coupled receptors (GPCRs) represent the largest family of cell-surface receptors. These receptors are natural allosteric proteins because agonist-mediated signaling by GPCRs requires a conformational change in the receptor protein transmitted between two topographically distinct binding sites, one for the agonist and another for the G protein. It is now becoming increasingly recognize...
متن کاملComplexing membrane for uranium detection by total reflection X-ray fluorescence.
Selective membranes containing a few micrograms of various complexing reagents in a polyvinyl chloride (PVC) matrix were produced in order to determine low uranium concentrations in water. The membranes were produced on the surfaces of quartz glasses, and immersed in water solutions containing uranium salts (5 - 50 ng/mL). By the end of the equilibration time, the membranes were left to dry and...
متن کاملfeatures of short story in translated and non-translated literature: a polysystemic perspective
ترجمه متون ادبی در دنیای امروز از اهمیت ویژه ای برخوردار است. فرهنگ های مختلف با استفاده از متون ادبی ملل و فرهنگ های دیگر سعی در غنی کردن فرهنگ و ادبیات کشور خود دارند. کشور ما نیز از این قاعده مستثنی نیست. در ایران، ترجمه متون ادبی اروپائی که با دوران مشروطه ایرانی آغاز می شود موجب تغییرات اساسی در فرهنگ، شیوه زندگی و تفکر ایرانیان شده است. در این دوران نه تنها در امورات سیاسی و فکری کشور تغی...
15 صفحه اولComplexing reverse transcriptase with polyspermine-ribonuclease.
Polyspermine-ribonuclease (Mr approximately 17 000) and the enzyme transcriptase from Rauscher-leukaemia virus (Mr approximately 70 000) form a complex Mr approx. 160 000) such that the molar ratio of polyspermine-ribonuclease to reverse transcriptase is 5:1. The most favourable condition for complex-formation is in a solution consisting of 0.01 M-Tris/HCl buffer, pH 7.5, 0.25 M-KCl and 1 mM-Mn...
