质膜ATPase在代谢能与驱动植物细胞表面溶质运输的工作的耦合中起着核心作用。虽然K+转运到植物细胞的机制尚不清楚，但很明显，K+与质膜H转运ATPase特异地相互作用。这种K+相互作用与在其他膜相关的ATPase中观察到的有许多相似之处，这些ATPase直接运输这种阳离子。虽然重组技术可能为质膜W转运ATPase在K+转运中的直接作用提供证据，但不应忽视自然膜中可能存在多种K+转运模式的可能性。
The plasma membrane ATPase has a central role in the coupling of metabolic energy to the work of driving solute transport at the surface of plant cells. While the mechanism of K+transport into plant cells is yet uncertain, it is clear that K+interacts specifically with the plasma membrane H-transporting ATPase. This K+interaction shows many similarities to what is observed in other membrane-associated ATpases which directly transport this cation. While reconstitution techniques may provide evidence for a direct role of the plasma membrane W-transporting ATPase in K+transport, the possibility that multiple modes of K+transport might exist in the native membrane should not be overlooked.
