Structural hierarchy of several proteins observed by wide‐angle solution scattering

Structural hierarchy of several proteins observed by wide‐angle solution scattering In the present study using a high‐intensity X‐ray beam from a third‐generation synchrotron radiation source, it is demonstrated that a wide‐angle X‐ray scattering (WAXS) profile from several globular proteins in solution can reflect not only the overall structures (∼300 Å distance resolution) but also intramolecular structures ranging to secondary structures (∼2.5 Å distance resolution). The proteins treated in the present experiments are classified as different types of structure categories, namely, as all‐α, all‐β and α + β proteins. Here the full‐range experimental scattering curves are compared with the theoretical curves, suggesting a further availability of the SR‐WAXS method for studies of structure hierarchy and the function of proteins in solutions. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Synchrotron Radiation Wiley

Abstract

In the present study using a high‐intensity X‐ray beam from a third‐generation synchrotron radiation source, it is demonstrated that a wide‐angle X‐ray scattering (WAXS) profile from several globular proteins in solution can reflect not only the overall structures (∼300 Å distance resolution) but also intramolecular structures ranging to secondary structures (∼2.5 Å distance resolution). The proteins treated in the present experiments are classified as different types of structure categories, namely, as all‐α, all‐β and α + β proteins. Here the full‐range experimental scattering curves are compared with the theoretical curves, suggesting a further availability of the SR‐WAXS method for studies of structure hierarchy and the function of proteins in solutions.
