Stoichiometry of sodium-calcium exchange in cardiac sarcolemmal vesicles. Coupling to the sodium pump.

B J Pitts.   

Abstract

Vesicles isolated from cardiac muscle exhibited Na,Ca exchange activity which can be measured by 45Ca influx or efflux of by 22Na efflux. The stoichiometry of Na,Ca exchange was 3 Na:1 Ca. These vesicles also exhibited ATP-dependent 22Na transport which was inhibited by ouabain indicating that this activity is due to the sodium pump, an activity which is thought to reside only in the sarcolemma. The addition of calcium caused rapid efflux of 22Na from vesicles loaded by ATP-dependent 22Na uptake indicating that the Na,Ca exchange is located in the same vesicles as the sodium pump and is thus also a sarcolemmal activity.
