Natural-abundance 207Pb NMR spectra (104.435 MHz) of PbII-bound three-strand coiled-coil peptides (10–12 mM): a) Pb-(BabyL12C)3−, b) Pb(CSL12C)3−, c) Pb(CSL16C)3−, d) Pb(CSL12AL16C)3−, e) Pb2(GrandL12AL16L26C)32−, f) Pb(Grand-L12AL16L26C)3−. All spectra were recorded for 10–12 h using natural-abundance Pb(NO3)2, (207Pb = 22.6%), pH 7.35 ± 0.05, at 25°C.
