Protein Repeat Identification by Graph Spectral Analysis

PRIGSA2 is a graph based algorithm which implements knowledge-based and de novo approach for the identification of structural repeats in proteins. The tool takes PDB file as input and gives the periodicity and coordinates as output.



Note: Cα network is suitable for identification of repeats in single chain, while atom pair contact is suitable for identification of multimeric repeats.
