Hybrid polymer-peptide conjugates offer the potential for incorporating biological function into synthetic materials. The secondary structure of short helical peptides, however, frequently becomes less stable when expressed independent of longer protein sequences or covalently linked with a conformationally disordered synthetic

In the search for a cell-instructive or cell-interactive artificial extracellular matrix, synthetic hydrogels have been extensively investigated to apply three-dimensional (3D) cell culture and tissue engineering. Here, we are reporting a reverse thermal gelling l/dl-polyalanine block copolymer aqueous solution for

L-alanine ethyl ester was polymerized into poly(L-alanine) (polyAla), one of the insoluble polypeptides, by papain in aqueous buffer at varying pH. At neutral pH, a maximum chain length of 11 repeats was observed. These polymers were dominated by random coiled

A new two-state polymer folding model is proposed, in which the folding of a stiff helical polymer is enabled by allowing for short sequences of coils connecting shorter and separated helices. The folding is driven by short-range attraction energy among
