The bacteriorhodopsin transport cycle includes protonation of the retinal Schiff base by Asp96 (M-->N reaction) and reprotonation of Asp96 from the cytoplasmic surface (N-->N' reaction). We measured distance changes between pairs of spin-labeled structural elements of interest, and in general observed larger overall structural changes in the N state compared with the N' state. The distance between the C-D loop and E-F interhelical loops in A103R1/M163R1 increased approximately 6 A in the N state ...[more]
