Abstract excerpt
Fourier-transform infrared spectra were recorded at 170 K before and after irradiating the Asp85-->Asn mutant of bacteriorhodopsin. The difference spectrum exhibits protein bands such as those due to the perturbations of Asp96 and Asp115 and the N-H stretching vibration of tryptophan, characteris...
