Alkalinity of Neutrophil Phagocytic Vacuoles Is Modulated by HVCN1 and Has Consequences for Myeloperoxidase Activity.

, 2015
The NADPH oxidase of neutrophils, essential for innate immunity, passes electrons across the phagocytic membrane to form superoxide in the phagocytic vacuole.

Biochemical, Structural and Physiological Characteristics of Vacuolar H+-Pyrophosphatase [PDF]

, 2018
Proton-translocating inorganic pyrophosphatase (H^+-PPase) actively translocates protons across membranes coupled with the hydrolysis of inorganic pyrophosphate (PPi).

Structural properties of vacuolar proton pumps

, 1990
It is well established that acidification within the collecting duct system is effected by means of a sodium-independent, electrogenic proton translocating ATPase [1].

Identification of a Domain in the Vo Subunit d That Is Critical for Coupling of the Yeast Vacuolar Proton-translocating ATPase [PDF]

Journal of Biological Chemistry, 2006
Vacuolar proton-translocating ATPase pumps consist of two domains, V(1) and V(o). Subunit d is a component of V(o) located in a central stalk that rotates during catalysis. By generating mutations, we showed that subunit d couples ATP hydrolysis and proton transport.

Evolutionary links between FliH/YscL-like proteins from bacterial type III secretion systems and second-stalk components of the FoF1 and vacuolar ATPases

, 2006
Bacterial type III secretion drives flagellar biosynthesis and mediates bacterial-eukaryotic interactions. Type III secretion is driven by an ATPase that is homologous to the catalytic subunits of proton-translocating ATPases, such as the FoF1 ATPase ...

Interaction of dibutyltin-3-hydroxyflavone bromide with the 16 kDa proteolipid indicates the disposition of proton translocation sites of the vacuolar ATPase [PDF]

Biochemical Journal, 1996
The organotin complex dibutyltin-3-hydroxyflavone bromide [Bu2Sn(of)Br] has been shown to bind to the 16 kDa proteolipid of Nephrops norvegicus, either in the form of the native protein or after heterologous expression in Saccharomyces and assembly into a hybrid vacuolar H+-ATPase.

Biochemical, cytochemical localization and physiological studies on Malpighian tubules of Locusta Migratoria L. [PDF]

, 1997
Specific inhibitors of protein kinase A (PKA), Rp-cAMP, protein kinase C (PKC), chelerythrine and staurosporine, and protein phosphatase 1 and 2A okadaic acid, inhibited fluid secretion whilst corpora cardiaca (CC) extract and cAMP were found to ...

The Yeast Vacuolar Proton-translocating ATPase Contains a Subunit Homologous to the Manduca sexta and Bovine e Subunits That Is Essential for Function [PDF]

Journal of Biological Chemistry, 2004
The yeast cwh36Delta mutant was identified in a screen for yeast mutants exhibiting a Vma(-) phenotype suggestive of loss of vacuolar proton-translocating ATPase (V-ATPase) activity. The mutation disrupts two genes, CWH36 and a recently identified open reading frame on the opposite strand, YCL005W-A.

A new type of Na+-driven ATP synthase membrane rotor with a two-carboxylate ion-coupling motif [PDF]

, 2013
: The anaerobic bacterium Fusobacterium nucleatum uses glutamate decarboxylation to generate a transmembrane gradient of Na+. Here, we demonstrate that this ion-motive force is directly coupled to ATP synthesis, via an F1Fo-ATP synthase with a novel Na ...
