Pre-Steady-State Kinetics of Ba-Ca Exchange Reveals a Second Electrogenic Step Involved in Ca(2+) Translocation by the Na-Ca Exchanger

Kinetic properties of the Na-Ca exchanger (guinea pig NCX1) expressed in Xenopus oocytes were investigated with excised membrane patches in the inside-out configuration and photolytic Ca(2+) concentration jumps with either 5 mM extracellular Sr(2+) or Ba(2+). After a Ca(2+) concentration jump on the...
