WebbThe structure of a mammalian proton-translocating transhydrogenase in various conformations is solved by cryo-electron microscopy, and a mechanism for the coupling process within the enzyme is proposed. NADPH is used as a reducing agent in many anabolic reactions. Proton translocating NAD(P) transhydrogenase is one of the main ways that cells can regenerate NADPH after it is used. In E. coli, this pathway contribute equal amounts of NADPH as the pentose phosphate pathway, and both were the main producers of … Visa mer Proton-Translocating NAD(P) Transhydrogenase (E.C. 7.1.1.1) is an enzyme in that catalyzes the translocation of hydrons that are connected to the redox reaction NADH + NADP + H outside => NAD + NADPH + H … Visa mer EC 7 – Translocases are a grouping of enzymes with a common function of assisting to move a molecule, typically across a membrane. Visa mer The transhydrogenase is found in the inner mitochondrial membranes of all vertebrates excluding fish. While it is not found in the yeast Saccharomyces cervisiae, it is found in algae such as Acetabularia acetabulum, as well as in the cytosolic membrane … Visa mer This enzyme’s structure is tied to its function heavily. The transmembrane domain in dII formed by alpha helices lends itself well to its function as a proton channel across a membrane. The lid and fingerprint motifs used by dIII to increase affinity to NADP(H) … Visa mer The reaction that this enzyme catalyzes is NADH + NADP + H outside => NAD + NADPH + H inside This redox reaction is a transfer of hydride equivalents from NADH to NADP coupled to a translocation of protons across a membrane. NADP is … Visa mer The structure of proton-translocating NADP(+) transhydrogenase has been shown to vary between organisms. The structures of the enzyme share an architecture with 3 … Visa mer
