Vibrational studies of the disulfide group in proteins. VII. Normal mode analysis of the Raman spectra of erabutoxin, γ‐II crystallin and immunoglobulin

By Weili Qian and Samuel Krimm


Normal mode calculations have been made on the known structures of disulfide bridges in erabutoxin b, a form of γ‐II crystallin, and fragments (Fab, variable‐domain of Bence‐Jones proteins) of immunoglobulins. Previously obtained Raman spectra of these molecules are analyzed in terms of general correlations derived from normal mode calculations and also the results of calculations on these particular structures. This results in more specific conclusions about these disulfide bridge structures and their changes than was possible on the basis of previous empirical correlations
