ATP synthase subunit 6 (eukaryotes),also subunit A (prokaryotes); Bacterial forms should be designated ATP synthase, F0 subunit A; eukaryotic (chloroplast and mitochondrial) forms should be designated ATP synthase, F0 subunit 6. The F1/F0 ATP synthase is a multisubunit, membrane associated enzyme found in bacteria and mitochondria and chloroplast. This enzyme is principally involved in the synthesis of ATP from ADP and inorganic phosphate by coupling the energy derived from the proton electrochemical gradient across the biological membrane. A brief description of this multisubunit enzyme complex: F1 and F0 represent two major clusters of subunits. Individual subunits in each of these clusters are named differently in prokaryotes and in organelles e.g., mitochondria and chloroplast. The bacterial equivalent of subunit 6 is named subunit 'A'. It has been shown that proton is conducted though this subunit. Typically, deprotonation and reprotonation of the acidic amino acid side-chains are implicated in the process.

ATP synthase Fo complex, subunit 6 (eukaryotes) and subunit a (prokaryotes); Bacterial forms are designated as ATP synthase, Fo complex, subunit a; eukaryotic (chloroplast and mitochondrial) forms are designated as ATP synthase, Fo complex, subunit 6. The F-ATP synthases (also called FoF1-ATPases) consist of two structural domains: F1 (factor one) complex containing the soluble catalytic core, and Fo (oligomycin sensitive factor) complex containing the membrane proton channel, linked together by a central stalk and a peripheral stalk. F-ATP synthases are primarily found in the inner membranes of eukaryotic mitochondria, in the thylakoid membranes of chloroplasts or in the plasma membranes of bacteria. F-ATP synthase has also been found in the archaea Methanosarcina acetivorans. F-ATP synthases are the primary producers of ATP, using the proton gradient generated by oxidative phosphorylation (mitochondria) or photosynthesis (chloroplasts). Alternatively, under conditions of low driving force, ATP synthases function as ATPases, thus generating a transmembrane proton or Na(+) gradient at the expense of energy derived from ATP hydrolysis.

Click on the triangle to view details about the feature, including a multiple sequence alignment
of your query sequence and the protein sequences used to curate the domain model,
where hash marks (#) above the aligned sequences show the location of the conserved feature residues.
The thumbnail image, if present, provides an approximate view of the feature's location in 3 dimensions.

This image shows a graphical summary of conserved domains identified on the query sequence.
The Show Concise/Full Display button at the top of the page can be used to select the desired level of detail: only top scoring hits
(labeled illustration) or all hits
(labeled illustration).
Domains are color coded according to superfamilies
to which they have been assigned. Hits with scores that pass a domain-specific threshold
(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.
click on the bars or triangles to view your query sequence embedded in a multiple sequence alignment of the proteins used to develop the corresponding domain model.
The table lists conserved domains identified on the query sequence. Click on the plus sign (+) on the left to display full descriptions, alignments, and scores.
Click on the domain model's accession number to view the multiple sequence alignment of the proteins used to develop the corresponding domain model.

(labeled illustration) Full Display shows all domain models, in each hit category below, that meet or exceed the RPS-BLAST threshold for statistical significance.
(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:
specific hits meet or exceed a domain-specific e-value threshold
(illustrated example)
and represent a very high confidence that the query sequence belongs to the same protein family as the sequences use to create the domain model
non-specific hits
meet or exceed the RPS-BLAST threshold for statistical significance (default E-value cutoff of 0.01, or an E-value selected by user via the
advanced search options)
the domain superfamily to which the specific and non-specific hits belong
