The structure of crystalline and membrane-bound gramicidin A by vibrational analysis
Biochemical and Biophysical Research Communications
|December 28, 1984
Abstract:
The results of normal mode calculations on the beta 4.4, beta 6.3, beta 5.6, and beta 7.2 structures of gramicidin A are compared with infrared and Raman spectra of crystalline native, crystalline Cs+-bound, and vesicle-bound gramicidin A. The observed frequencies and frequency splittings are in good agreement with an assignment of beta 5.6, beta 7.2, and beta 6.3 structures, respectively, to the gramicidin A molecules in the above three systems.
