F-ATPase, also known as F-Type ATPase, is an ATPase/synthase found in bacterial plasma membranes, in mitochondrial inner membranes (in oxidative phosphorylation, where it is known as Complex V), and in chloroplast thylakoid membranes. It uses a proton gradient to drive ATP synthesis by … See more Fo-F1 particles are mainly formed of polypeptides. The F1-particle contains 5 types of polypeptides, with the composition-ratio—3α:3β:1δ:1γ:1ε. The Fo has the 1a:2b:12c composition. Together they form a rotary … See more N-ATPases are a group of F-type ATPases without a delta/OSCP subunit, found in bacteria and a group of archaea via horizontal gene transfer.

WebThe V-ATPase, a complicated multi-subunit ATPase similar to the F-ATPase (Fig. 1), has both a membrane extrinsic V 1 catalytic complex and transmembrane V 0 proton pathway. The V-ATPase hydrolyzes ATP to ADP and Pi coupling this to H + transport through rotation of a rotor stalk. This proton pump, expressed ubiquitously in yeast, mammalian, insect, … WebV-ATPases are the primary source of organellar acidification in all eukaryotes, making them essential for many fundamental cellular processes. Enzymatic activity can be modulated by regulated and reversible disassembly of the complex, and several subunits of mammalian V-ATPase have multiple isoforms that are differentially localized. e-learning bmjWebJul 22, 2024 · ATPase (Left), UV-visible spectrum (Middle), and heme transfer (Right).
