The nomenclature and descriptions of the peptides used in the study

Peptide name	Description
ZIF (Z)	The three fingers of Zif268
MUT (M)	A three-finger mutant of Zif268
3 × 2F ZMS	A six-finger peptide of Z fused N-terminally to M using the linker sequence -TGERP-, which contains a single glycine insertion within the linkers between fingers 2 and 3 and between fingers 4 and 5
3 × 2F ZML	As above, but with -gly, ser, gly- insertions instead of a single glycine
3 × 2F ZMSL	As above, but with a single glycine insertion in the linker between fingers 1 and 2, and a -gly, ser, gly- insertion between fingers 4 and 5
3 × 2F ZMLS	As above, but with a -gly, ser, gly- insertion between fingers 1 and 2 and a single glycine insertion between fingers 4 and 5
2 × 3F ZM	A six-finger peptide of Z fused N-terminally to M using the linker sequence -LRQKDGERP- between fingers 3 and 4
