WebMultiple subunits form H(+)-ATPases, with proteins of the V1 class hydrolyzing ATP for energy to transport H+, and proteins of the V0 class forming an integral membrane domain through which H+ is transported. ATP6V0E2 encodes an isoform of the H(+)-ATPase V0 e subunit, an essential proton pump component (Blake-Palmer et al., 2007). WebFeb 15, 2006 · SUMMARY. It was nearly 30 years before the V-type H+ ATPase was admitted to the small circle of bona fide transport ATPases alongside F-type and P-type ATPases. The V-type H+ ATPase is an ATP-driven enzyme that transforms the energy of ATP hydrolysis to electrochemical potential differences of protons across diverse …
H+-transporting two-sector ATPase - Creative Enzymes
WebMembrane-bound inorganic pyrophosphatase (mPPase) resembles the F-ATPase in catalyzing polyphosphate-energized H+ and Na+ transport across lipid membranes, but differs structurally and mechanistically. Homodimeric mPPase likely uses a “direct coupling” mechanism, in which the proton generated from the water nucleophile at the entrance to … WebHowever, Altman et al suggested that H + /K + ATPases are transmembrane enzymes mainly responsible for the transport of ions, similar to V-type ATPases. 42–44 A similarity of the laryngeal proton pump H + /K + ATPase to the V-type ATPase in rodent seromucinous glands has also been reported. 42–45 These findings may be of clinical ... pale blue bath mat set

WebATPase ATPases are a class of enzymes that catalyze the decomposition of adenosine triphosphate (ATP) into adenosine diphosphate (ADP) and a free ... (F-, V- and A-ATPases contain rotary motors) and in the type of ions they transport. F-ATPases (F1F0-ATPases) in mitochondria, chloroplasts and bacterial plasma membranes are the prime producers ... WebAug 1, 2011 · P-type ATPases are a large family of integral membrane transporters that are of vital importance in all kingdoms of life. In eponymous distinction from the other main classes of transport ATPase – the F 0 F 1 (F-), the vacuolar (V-) and the ATP-binding cassette (ABC-) type – the P-type ATPases form a phosphorylated (P-) intermediate … Web7.1.2.2 H+-transporting two-sector ATPase KN400_0086 (atpA) 7.2 Catalysing the translocation of inorganic cations 7.2.2 Linked to the hydrolysis of a nucleoside … pale blue band
