Looking for central tendencies in the conformational freedom of proteins using NMR measurements
نویسندگان
چکیده
We study the conformational freedom of a protein made by two rigid domains connected by a flexible linker. The conformational freedom is represented as an unknown probability distribution on the space of allowed states. A new algorithm for the calculation of the Maximum Allowable Probability is proposed, which can be extended to any type of measurements. In this paper we use Pseudo Contact Shifts and Residual Dipolar Coupling. We reconstruct a single central tendency in the distribution and discuss in depth the results.

Conformational Study of some novel Methoxy Half-Analogues of Michler’s Ketone by NMR
One series of half-analogues of Michler’s ketone containing one or more terminal methoxysubstituents with variable tertiary amino groups have been used in this study. NMR spectralresults for the parent ketones confirm earlier findings that ortho proton shifts are apparentlyindependent from steric effects in derivatives of Michler’s ketone because the ring current andcarbonyl-induced shifts are ...

Estimation of protein stability is important for many reasons: first providing an understanding of the basic thermodynamics of the process of folding, protein engineering, and protein stability plays important role in biotechnology especially in food and protein drug design. Today, proteins are used in many branches, including industrial processes, pharmaceutical industry, and medical fields. A...
متن کاملPredictive atomic resolution descriptions of intrinsically disordered hTau40 and α-synuclein in solution from NMR and small angle scattering.
The development of molecular descriptions of intrinsically disordered proteins (IDPs) is essential for elucidating conformational transitions that characterize common neurodegenerative disorders. We use nuclear magnetic resonance, small angle scattering, and molecular ensemble approaches to characterize the IDPs Tau and α-synuclein. Ensemble descriptions of IDPs are highly underdetermined due t...

متن کاملThe Ratio of Political Goodness and Negative Freedom in Berlin's Political Thought (With Emphasis on Russian Communism)
The present article aims to examine Isaiah Berlin's views and ideas, and gives answers to the questions of how political goodness is linked to the concept of negative liberty in Berlin's thought, and how his view of political goodness has formed his critique looking toward the political system of the Soviet Union. Political goodness in Berlin's thought seems to be multiplied, and from the plur...
