Beta-sheet
The addition of tfe most likely caused secondary structural alterations in the peptide. the poly-L-secondary lysine's structure evolved from a beta sheet.
What is Beta-sheet ?
A typical motif of the typical protein secondary structure is the beta sheet, sometimes known as the "sheet" or "pleated sheet." Beta sheets are made up of beta strands (-strands) that are joined laterally by two or three backbone hydrogen bonds, resulting in a sheet that is typically twisted and pleated. A section of polypeptide chain known as a "-strand" has a backbone that is stretched and is typically 3 to 10 amino acids long. It has been suggested that the supramolecular connection of -sheets contributes to the development of the fibrils and protein aggregates seen in amyloidosis, particularly Alzheimer's disease.
