TABLE 1

Summary of cross-linking reaction of single and double mutants of 3Cys ΔMRP1

Numbers correspond to the thiosulfonate reagent that cross-linked cysteine residues in a given mutant. For instance, “5” corresponds to M5M. Dash (–) indicates no cross-linked product detected with any of the three cross-linkers. Empty cells indicate that the cross-linking reactions were not performed.
