Database Description

FSN (Flexible Structural Neighborhood) is a database of protein structural similarities and alignments. It employs the flexible protein structure alignment program, FATCAT, to define similarities between all protein structures deposited in the PDB. The FSN interface enables the efficient retrieval of lists of proteins with statistically significant structural similarity to protein or domain queries (via their PDB or SCOP identifiers, respectively). The server also allows users to analyze the identified structural neighbors by providing detailed alignments, interactive superposition of structures and highlighting hinge positions identified by flexible structural comparison. FSN is a unique resource to support the analysis of protein structure, and may prove valuable in unveiling the rules that govern protein change and evolution.

Recent Developments

Jmol view has been added to the standard Chime view of protein structure superposition.
