RMSD between structures

From Proteopedia

The root mean square deviation (RMSD) "is a measure of the average deviation in distance between aligned Cα atoms in 3D superimposition. For sequences sharing 50% identity, this should be around 1.0 [Å]."^[1]. Similarly, the RMSD between two independently-determined X-ray crystallography structures of the same protein is typically about 1.0 Å.
