Conformational properties of a polyglycine chain with secondary and tertiary structures of lysozyme

Unperturbed dimension mean value of r2(0), dipole moment mean value of mu2, mean squared optical anisotropy mean value of gamma 2 and molar Kerr mean value of mK constant of a polyglycine chain with the secondary and tertiary structures of lysozyme have been calculated and the results compared with polyglycine chains with the same number of repeat units but different conformations including alpha-helix, beta-sheet or random coil. Thus, the influence of secondary and tertiary structures can be investigated. The results obtained show that for mean value of r2 and mean value of gamma 2 this influence is at least of the same order of magnitude as that of the primary structure, and is much greater for mean value of mu 2 and mean value of mK.
