As an A subunit, MT-ATP8 is contained within the non-catalytic, transmembrane F o portion of the complex, comprising the proton channel. The catalytic portion of mitochondrial ATP synthase consists of 5 different subunits (alpha, beta, gamma, delta, and epsilon) assembled with a stoichiometry of 3 alpha, 3 beta, and a single representative of ...
The alpha/beta subunits undergo a sequence of conformational changes leading to the formation of ATP from ADP, which are induced by the rotation of the gamma subunit, itself is driven by the movement of protons through the Fo complex C subunit. [7] In V- and A-ATPases, the alpha/A and beta/B subunits of the V1 or A1 complex are homologous to ...
The c-ring is tightly attached to the asymmetric central stalk (consisting primarily of the gamma subunit), causing it to rotate within the alpha 3 beta 3 of F 1 causing the 3 catalytic nucleotide binding sites to go through a series of conformational changes that lead to ATP synthesis.
The α subunit is close to the subunit b 2 and makes up the stalk that connects the transmembrane subunits to the α3β3 and δ subunits. F-ATP synthases are identical in appearance and function except for the mitochondrial F 0 F 1 -ATP synthase, which contains 7-9 additional subunits.
With respect to the MT-ATP6 reading frame (+3), the MT-ATP8 gene ends in the +1 reading frame with a TAG stop codon. The MT-ATP6 protein weighs 24.8 kDa and is composed of 226 amino acids . [ 8 ] [ 9 ] The protein is a subunit of the F 1 F o ATPase, also known as Complex V , which consists of 14 nuclear- and 2 mitochondrial-encoded subunits.
[7] [8] The protein is a subunit of the catalytic portion of the F 1 F o ATPase, also known as Complex V, which consists of 14 nuclear and 2 mitochondrial -encoded subunits. As an alpha subunit, ATP5F1A is contained within the catalytic F 1 portion of the complex. [6] The nomenclature of the enzyme has a long history.

Schematic demonstrating mitochondrial fatty acid beta-oxidation and effects of long-chain 3-hydroxyacyl-coenzyme A dehydrogenase deficiency, LCHAD deficiency. Mitochondrial trifunctional protein (MTP) is a protein attached to the inner mitochondrial membrane which catalyzes three out of the four steps in beta oxidation.
