Acid assists digestion. That this is true at the subcellular as well as the organismal level was recognized more than 90 years ago by Metchnikoff (1893), who observed that blue litmus turned red when engulfed by protozoans. Today it is universally recognized that lysosomes, the intracellular digestive organelles, show an internal pH approximately 2 ...

Journal of Bioenergetics and Biomembranes, 1989
Recently a new class of proton-translocating ATPases has been localized to endomembrane compartments in plant, fungal, and mammalian cells. These proton pumps are large hetero-oligomers which have an ATP hydrolytic sector that is functionally and structurally distinct from a transmembranous proton pore.

Hypomagnesemia and proton-pump inhibitors
Expert Opinion on Drug Safety, 2013Proton pump inhibitors (PPIs) have been linked to clinically symptomatic hypomagnesemia.We searched Medline database in all languages using 'proton-pump inhibitors, magnesium, hypomagnesemia and hypomagnesemic hypoparathyroidism' as search terms and other articles were identified through searches of the files of the authors and reference lists from ...

Deprescribing proton pump inhibitors
Australian Journal of General Practice, 2022Proton pump inhibitors (PPIs) are indicated for disorders including peptic ulcer disease and gastro-oesophageal reflux disease; however, they are often used for longer and at higher doses than recommended, or for indications that are not supported by evidence.The aim of this article is to outline evidence-based approaches to deprescribing PPIs.PPIs are

Reconstitution of a Proton Pump
Biochemical Society Transactions, 1976The retinal-protein complex bacteriorhodopsin mediates lightxnergy conversion in halobacteria. This chromoprotein is embedded in the cell membrane and forms insular regions. These can be isolated by membrane-fractionation procedures, and they consist of a lipid matrix containing bacteriorhodopsin molecules in a hexagonal crystalline arrangement called ...

Protons and how they are transported by proton pumps
Pflügers Archiv - European Journal of Physiology, 2008The very high mobility of protons in aqueous solutions demands special features of membrane proton transporters to sustain efficient yet regulated proton transport across biological membranes. By the use of the chemical energy of ATP, plasma-membrane-embedded ATPases extrude protons from cells of plants and fungi to generate electrochemical proton ...
