Table 2. The values of Stern–Volmer quenching constants for Trp 32 residue of all the protein variants in the absence (K_sv,M⁻¹) and presence of DPPC SUVs (K_svm, M⁻¹) as obtained from acrylamide quenching for WT SOD1 and all the mutants including apo SOD1.

WT SOD1	6.8 ± 0.1	5.7 ± 0.2	1.19
H121F	8.0 ± 0.1	6.3 ± 0.1	1.26
H72F	12.7 ± 0.3	7.0 ± 0.2	1.82
apo SOD1	14.3 ± 0.1	7.6 ± 0.2	1.88
