Subunit structure and dual ATP effects of Na, K-ATPase
The Na,-ATPase activity of membrane-bound sodium pump exhibits non-Michaelis kinetics with respect to ATP. The enzyme consists of promoters (one plus one -subunit) that may be organised into higher oligomers. Each -subunit is believed (although it has

Transcriptomic changes triggered by ouabain in rat cerebellum granule cells: Role of α3- and α1-Na+,K+-ATPase-mediated signaling [PDF]
It was shown previously that inhibition of the ubiquitous α1 isoform of Na+,K+-ATPase by ouabain sharply affects gene expression profile via elevation of intracellular [Na+]i/[K+]i ratio.

Some effects of insect hormones on Na(^+), K(^+)-ATPase and fluid secretion by the malpighian tubules of locusta migratoria L [PDF]
A study has been made on the effects of insect hormones on fluid secretion by the Malpighian tubules of Locusta, and on the Na(^+), K(^+)- ATPase activity in microsomal preparations of the tubules.

V-ATPase is the dominant proton pump in plant cells. It contributes to cytosolic pH homeostasis and energizes transport processes across endomembranes of the secretory pathway. Its localization in the trans Golgi network/early endosomes is essential for vesicle transport, for instance for the delivery of cell wall components. Furthermore, it is crucial

Features of V‐ATPases that distinguish them from F‐ATPases [PDF]
The general structure of F‐ and V‐ATPases is quite similar and they may share a common mechanism of action that involves mechanochemical energy transduction. Both holoenzymes are composed of catalytic sectors, F1 and V1 respectively, and membrane sectors, Fo and Vo respectively. Although we assume that a similar mechanism underlies ATP‐dependent proton

ATPase mechanism of the 5'-3' DNA helicase, RecD2: evidence for a pre-hydrolysis conformation change [PDF]
The superfamily 1 helicase, RecD2, is a monomeric, bacterial enzyme with a role in DNA repair, but with 5'-3' activity unlike most enzymes from this superfamily. Rate constants were determined for steps within the ATPase cycle of RecD2 in the presence of

Autolysosome biogenesis and developmental senescence are regulated by both Spns1 and v-ATPase
Spns1 (Spinster homolog 1 [Drosophila]) in vertebrates, as well as Spin (Spinster) in Drosophila, is a hypothetical lysosomal H+-carbohydrate transporter, which functions at a late stage of macroautophagy (hereafter autophagy).
