Some of those local folds form precise, regular structures, often stabilised by hydrogen bonds. WebThe directory of secondary structure of proteins (DSSP) is a tool used to measure the evolution of the secondary structure content of a protein with time. The tool is based on the DSSP library designed by Kabsch and Sander [55,56]. DSSP is a database for secondary structure assignments but does not predict the secondary structure of the proteins.

WebPrimary Structure. The unique sequence of amino acids in a polypeptide chain is its primary structure.
