Probing subunit-subunit interactions in the yeast vacuolar ATPase by peptide arrays. [PDF]
PLoS ONE, 2012 BACKGROUND:Vacuolar (H(+))-ATPase (V-ATPase; V(1)V(o)-ATPase) is a large multisubunit enzyme complex found in the endomembrane system of all eukaryotic cells where its proton pumping action serves to acidify subcellular organelles. In the plasma membrane

Chemical aspect of the influence of cobalt ions on atpase activity [PDF]
Journal of the Serbian Chemical Society, 2000 The influence of Co 2+ ions on the activities of Na+/K+-ATPase and Mg2+ -ATPase, enzymes from rat brain synaptic plasma membrane, was studied. The aim of this study was to investigate the inhibition of both ATPases activities byexposure tocobalt

Molecular basis of mEAK7-mediated human V-ATPase regulation
Nature Communications, 2022 Structural basis of V-ATPase regulation by endogenous proteins is unclear. Here, the authors find mEAK7 as an endogenous V-ATPase modulator and determine its structure with V-ATPase, suggesting the potential role of mEAK7 in V-ATPase regulation.

All motors have to decide is what to do with the DNA that is given them
Biomolecular Concepts, 2014 DNA translocases are a diverse group of molecular motors responsible for a wide variety of cellular functions. The goal of this review is to identify common aspects in the mechanisms for how these enzymes couple the binding and hydrolysis of ATP to their

Function-related positioning of the type II secretion ATPase of Xanthomonas campestris pv. campestris. [PDF]
PLoS ONE, 2013 Gram-negative bacteria use the type II secretion (T2S) system to secrete exoproteins for attacking animal or plant cells or to obtain nutrients from the environment. The system is unique in helping folded proteins traverse the outer membrane.

Bacterial rotary export ATPases are allosterically regulated by the nucleotide second messenger cyclic-di-GMP [PDF]
, 2015 The widespread second messenger molecule cyclic di-GMP (cdG) regulates the transition from motile and virulent lifestyles to sessile, biofilm-forming ones in a wide range of bacteria. Many pathogenic and commensal bacterial-host interactions are known to

Expansion of Thaumarchaeota habitat range is correlated with horizontal transfer of ATPase operons. [PDF]
, 2019 Thaumarchaeota are responsible for a significant fraction of ammonia oxidation in the oceans and in soils that range from alkaline to acidic. However, the adaptive mechanisms underpinning their habitat expansion remain poorly understood.
