Figure 6From: Regulatory role of E-NTPase/E-NTPDase in Ca2+/Mg2+ transport via gated channelPhase II: Ca2+/Mg2+ Transport. (A) Three-dimensional impression of the E-NTPase/E-NTPDase in vivo. (B) It is possible that Ca2+ can enter the cell and excess Mg2+ can leave via the influx/efflux mechanisms depicted in the figure.Back to article page
