Abstract

A structural comparison between the Normal and the Expanded isomers of the human serum albumin has been carried out by using small angle X-ray scattering (SAXS) and light scattering (LS) techniques. Geometrical bodies, recovered structures (GA_STRUCT code) and rigid body modeling (CRYSOL and BUNCH software) were used to obtain low-resolution 3D structures from one-dimensional scattering patterns. These restored shapes were also exploited to perform a correlation between SAXS and LS data. By attempting a detailed description of globular and unfolded protein structures in solution, we tried to propose a suitable approach to follow the path of folding/unfolding processes and to isolate and characterize possible partially folded intermediate states.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
