Differences in the UVPD fragment intensity between apo-MscL and holo-MscL bound to five lipids plotted by (A) residue position and (B-D) on a subunit of the crystal structure. The circled regions showed the most significant variations between apo-MscL and holo-MscL. Reprinted from Sipe, S. N.; Patrick, J. W.; Laganowsky, A.; Brodbelt, J. S.
