Structure, function and regulation of the plant vacuolar H(+)-translocating ATPase

Biochim Biophys Acta. 2000 May 1;1465(1-2):17-36. doi: 10.1016/s0005-2736(00)00129-2.

Abstract

The plant V-ATPase is a primary-active proton pump present at various components of the endomembrane system. It is assembled by different protein subunits which are located in two major domains, the membrane-integral V(o)-domain and the membrane peripheral V(1)-domain. At the plant vacuole the V-ATPase is responsible for energization of transport of ions and metabolites, and thus the V-ATPase is important as a 'house-keeping' and as a stress response enzyme. It has been shown that transcript and protein amount of the V-ATPase are regulated depending on metabolic conditions indicating that the expression of V-ATPase subunit is highly regulated. Moreover, there is increasing evidence that modulation of the holoenzyme structure might influence V-ATPase activity.
