BriX Covers

BriX is a structural classification of protein fragments. The library comprises fragments ranging from 4 to 14 amino acids that are clustered against 6 different distance thresholds. This has lead to an alphabet of around 2000 frequently observed letters or structural classes per chain length. These classes are accessible through a search and a browse interface on the BriX website. The peptide is associated with its corresponding structural class from the database of protein fragment clusters (BriX). In these fragment clusters, sets of protein fragments with highly similar backbone structure are grouped. Each protein fragment class represents a natural variation on a typical backbone conformation, with a given length and starting from the given residue in the original peptide. To find out more, consult this help page.
