2.9.4. Radius of Gyration

Rg is the RMS distance between a group of atoms and their collective center of mass, and it is linked to a protein's tertiary structure stability. It is one of the most extensively used criteria for determining the compactness of a protein structure. The values of Rg of Rv1636 and the Rv1636\_*β*-amyrin complex were 1.42461 nm and 1.43199 nm, respectively. A minor increase in the Rg values of the Rv1636\_*β*-amyrin complex was directly in agreement with the RMSF values. The Rg plot suggested that Rv1636 protein was stably folded with the R1636\_*β*-amyrin complex, as shown in Figure 9c.
