Scaling behavior and structure of denatured proteins.
An ensemble of random-coil conformations with no persistent structures has long been accepted as the classical model of denatured proteins due to its consistency with the experimentally determined scaling of protein sizes. However, recent NMR spectroscopy studies on proteins at high chemical denaturant concentrations suggest the presence of significant amounts of native-like structures, in cont...
متن کاملHeat capacity and compactness of denatured proteins.
One of the striking results of protein thermodynamics is that the heat capacity change upon denaturation is large and positive. This change is generally ascribed to the exposure of non-polar groups to water on denaturation, in analogy to the large heat capacity change for the transfer of small non-polar molecules from hydrocarbons to water. Calculations of the heat capacity based on the exposed...
متن کاملAre denatured proteins ever random coils?
T polymer chemists, the term random coil means a chain molecule whose backbone coils randomly in three-dimensional space, with a conformation described by the Gaussian probability function (1). To protein chemists, the term random coil carries an added special meaning: the backbone conformation of every amino acid residue, described by its phi, psi pair of backbone angles, is independent of the...
متن کاملBinding of SecB to ribosome-bound polypeptides has the same characteristics as binding to full-length, denatured proteins.
The interaction of the chaperone SecB with ribosome-bound polypeptides that are in the process of elongation has been studied using an in vitro protein synthesis system. The binding is characterized by the same properties as those demonstrated for the binding of SecB to full-length proteins that are in nonnative conformation: it is readily reversible and has no specificity for the leader peptid...
متن کاملAggregation of adult and fetal hemoglobin by ingested nitrate anions
The ingested nitrates sourced from tap water, food, chemicals and pharmaceuticals areconverted to nitrites in the body surfaces by bacteria and then, the nitrite ions can lead thestructural changing in hemoglobin. In the present work, aggregation of the purified hemoglobinin adult (HbA) and in fetus or newborn (HbF) in the presence of nitrite ions were studied.Hemoglobin aggregation was perform...
