WebFor a protein, the RMSD of all atoms is usually larger than the RMSD of C [math]\displaystyle{ \alpha }[/math] since the main chain is more constrained than the lateral chains of the amino acids. Tools. The following tool can be used to perform a sequence alignment of protein structures and then compute the corresponding RMSD. WebFor sequences with high identity (default >80%), SuperPose analyzes the DD matrix to look for dissimilar regions, defined by a stretch of 7-or-more aligned C-alpha pairs with RMSD over a certain cutoff (default 3 Angstroms). If a significant dissimilarity is found, SuperPose will perform a 'subdomain superposition'.

WebOct 1, 2004 · Both simulations of the peptide-bound class I form at 300 K and 355 K showed a stable Cα main chain Rmsd (root-mean square deviation) after ∼2–4 ns simulation time of ∼1.5–1.8 Å with respect to the start structure (Fig. 2 A).Even in case of the elevated temperature simulation (355 K) the peptide-bound form stayed relatively close to the start … WebIt depends on the input selections. If you don't restrict it to backbone atoms, PyMOL will perform the fit for all matched atoms. Also, it is important to understand that "align" is a combined sequence and 3D refined structure alignment which, by default, iteratively discards outliers in order to achieve a well-matched core structure.
