The proton pump ATPase of lysosomes and related organelles of the vacuolar apparatus.

In this review, I hope to achieve the following: (a) to document the presence of a lysosome-like proton pump ATPase in many different membrane systems of animal, plant and microbial origin; (b) to glean from the diverse data common characteristics of these ATPases, especially as regards their similarities and differences with mitochondrial-type F1F0 proton pump ATPases; and (c) to consider questions of synthesis and regulation of a cellular proton pump system with such a widespread distribution.
