Metals/Ions Comment Organism Structure
Cd2+ activation energy of binding is similar for both Pb2+ and Cd2+ Escherichia coli
additional information metal binding to the transmembrane site in ZntA or metal release from the transporter is the slow step in the reaction cycle. metal-binding to the N-terminal domain is not rate-limiting in the overall transport mechanism Escherichia coli
Pb2+ activation energy of binding is similar for both Pb2+ and Cd2+ Escherichia coli
