| Abstract: | FTIR difference spectroscopic studies of M intermediate and LA bacteriorhodopsin in the O-H stretching region show bands at 3671 and 3641 cm-1, respectively. The O-H stretching bands in this region may reflect protonation-deprotonation changes or environmental change in the tyrosine residues in bR. |
