By introducing an additional hydrogen bond to hydrogen bond interaction in the force field of the CSAW (Conditioned Self-Avoiding Walk) model, we investigate into the mechanism of antiparallel β-sheet formation based on the folding of a short polyalanine in gas

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

The amide I mode is a highly structure sensitive vibration of polypeptides that gives rise to a very strong band in IR absorption and a moderate band in Raman spectra. Many theoretical simulations of IR-band profiles have been undertaken thus

N-Acetylmuramyl-L-Ala-D-Glu-NH2 (muramyl dipeptide) and several of its derivatives are effective immunoactivators that can enhance nonspecific resistance to infection but can also elicit fever. In contrast, one of its stereoisomers, N-acetylmuramyl-D-Ala-D-Glu-NH2, is devoid of both these activities. Our present report demonstrates
