Anomalous amide I infrared absorption of purple membrane

KJ Rothschild and NA Clark

Infrared absorption of purple membrane reveals an amide I frequency that falls outside the range normally found for alpha helices. This may indicate along with x-ray diffraction the existence of bacteriorhodopsin alpha helices with unusual structure.
