A protein closely resembling the purple membrane protein pre-exists in the cell membrane of H. halobium prior to the appearance of functional bacteriorhodopsin. It is associated with a differentiated membranous structure which has been isolated on a sucrose gradient and appears to be a precursor of

Resonance Raman (RR) spectra were measured for the purple intermediates of D-amino acid oxidase reconstituted with isotopically labelled FAD's, i.e., [4a-13C]-, [4,10a-13C2]-, [2-13C]-, [5-15N]-, and [1,3-15N2]flavin adenine dinucleotides, and compared with those with the native enzyme. The RR lines
