Structural characterization of the molten globule state of apomyoglobin by limited proteolysis and HPLC-mass spectrometry.
A method to characterize the structural conformation of an acidic molten globule apomyoglobin (apoMb) at pH 4.2 was developed using limited proteolysis and HPLC-mass spectrometry (HPLC-MS). Endoproteinase Glu-C, which has a double maximum activity at pH 4.0 and pH 7.8 toward glutamic acid (Glu), was used as a proteolytic enzyme. Using this method enabled us to compare the proteolytic cleavages ...

هدف پژوهش حاضر ارائه ی الگویی بر اساس کنش گفتار و کارکرد زبان برای تدوین مطالب درس "بررسی آثار ترجمه شده ی اسلامی" می باشد. در الگوی جدید، جهت تدوین مطالب بهتر و جذاب تر، بر خلاف کتاب-های موجود، از مدل های سطوح گفتارِ آستین (1962)، گروه بندی عملکردهای گفتارِ سرل (1976) و کارکرد زبانیِ هالیدی (1978) بهره جسته شده است. برای این منظور، 57 آیه ی شریفه، به صورت تصادفی از بخش-های مختلف قرآن انتخاب گردید...
15 صفحه اولA comparison of the folding characteristics of free and ribosome-tethered polypeptide chains using limited proteolysis and mass spectrometry
The kinetics and thermodynamics of protein folding are commonly studied in vitro by denaturing/renaturing intact protein sequences. How these folding mechanisms relate to de novo folding that occurs as the nascent polypeptide emerges from the ribosome is much less well understood. Here, we have employed limited proteolysis followed by mass spectrometry analyses to compare directly free and ribo...
متن کاملIdentification of the binding surface on beta-lactamase for GroEL by limited proteolysis and MALDI-mass spectrometry.
Escherichia coli beta-lactamase, alone or as a complex with GroEL at 48 degreesC, was partially digested with trypsin, endoproteinase Glu-C, or thermolysin. Peptides were analyzed by matrix-assisted laser desorption and ionization mass spectrometry and aligned with the known sequence. From the protease cleavage sites which become protected upon binding and those which become newly accessible, a...
متن کاملTopography of succinate dehydrogenase in the mitochondrial inner membrane. A study using limited proteolysis and immunoblotting.
The arrangement of the large (70,000-Mr) and small (30,000-Mr) subunits of succinate dehydrogenase in the mitochondrial inner membrane was investigated by immunoblot analysis of bovine heart mitochondria (right-side-out, outer membrane disrupted) or submitochondrial particles (inside-out) that had been subjected to surface-specific proteolysis. Both subunits were resistant to proteinase treatme...
