Attachment of MTSL to unfolded Q48C apoflavodoxin in 6.0 M GuHCl causes the protein to behave in a more ordered fashion than random coil apoflavodoxin. Shown are the ratios between cross peak intensities of backbone amides of unfolded Q48CMTSL apoflavodoxin in the diamagnetic state (I MTSL) and unfolded Q48C apoflavodoxin (I nolabel), which are both in 6.0 M GuHCl. The ratio I MTSL/I nolabel of residue 179 is set to 1. The green dot indicates the position of the spin-label
