Pb2+is a xenobiotic metal ion that competes for Ca2+-binding sites in proteins. Using the peripheral Ca2+-sensing domains of Syt1, we show that the chelating pH buffer Bis–Tris enables identification and functional characterization of high-affinity Pb2+sites that are likely to be targeted by bioavailable Pb2+.
