Kinetics of Thermal Denaturation and Aggregation of Bovine Serum Albumin.
Thermal aggregation of bovine serum albumin (BSA) has been studied using dynamic light scattering, asymmetric flow field-flow fractionation and analytical ultracentrifugation. The studies were carried out at fixed temperatures (60°C, 65°C, 70°C and 80°C) in 0.1 M phosphate buffer, pH 7.0, at BSA concentration of 1 mg/ml. Thermal denaturation of the protein was studied by differential scanning c...
متن کاملUnfolding and aggregation during the thermal denaturation of streptokinase.
The thermal denaturation of streptokinase from Streptococcus equisimilis (SK) together with that of a set of fragments encompassing each of its three domains has been investigated using differential scanning calorimetry (DSC). Analysis of the effects of pH, sample concentration and heating rates on the DSC thermograms has allowed us to find conditions where thermal unfolding occurs unequivocall...
متن کاملEditor Note – Biochemistry & Analytical Biochemistry
Biochemistry is the study of structures, functions and interactions of biomolecules, such as carbohydrates, nucleic acids, proteins, lipids, etc. and their metabolisms. Advancements in biochemistry helps in the advancement of different fields like agriculture, medicine, nutrition, etc., which are directly related to it. Combination of biochemical techniques with techniques and ideas of genetics...
متن کاملThermal denaturation and aggregation of hemoglobin of Glossoscolex paulistus in acid and neutral media.
The thermal denaturation and aggregation of the HbGp, in the oxy- and cyanomet-forms, was investigated by DSC, AUC, DLS, optical absorption and CD, in the pH range from 5.0 to 7.0. Oxy-HbGp has a denaturation process partially reversible and dependent on the temperature. DSC melting curve is characterized by a single peak with T(c) value of 333.4 ± 0.2K for oxy-HbGp, while two peaks with T(c) v...
متن کاملThe Regulatory Subunit of PKA-I Remains Partially Structured and Undergoes β-Aggregation upon Thermal Denaturation
BACKGROUND The regulatory subunit (R) of cAMP-dependent protein kinase (PKA) is a modular flexible protein that responds with large conformational changes to the binding of the effector cAMP. Considering its highly dynamic nature, the protein is rather stable. We studied the thermal denaturation of full-length RIα and a truncated RIα(92-381) that contains the tandem cyclic nucleotide binding (C...
