Pb is a xenobiotic metal ion that competes for Ca-binding sites in proteins. Using the peripheral Ca-sensing domains of Syt1, we show that the chelating pH buffer Bis-Tris enables identification and functional characterization of high-affinity Pb sites that are likely to be targeted by bioavailable Pb.
铅是一种异生物质金属离子，它与蛋白质中的钙结合位点竞争。我们使用 Syt1 的外周钙感应结构域表明，螯合 pH 缓冲剂 Bis-Tris 能够识别和功能表征高亲和力的铅结合位点，这些结合位点可能是生物可利用的铅的靶标。
