Abstract

The alpha- and beta-subunits of membrane-bound ATP synthase complex bind ATP and ADP: beta contributes to catalytic sites, and alpha may be involved in regulation of ATP synthase activity. The sequences of beta-subunits are highly conserved in Escherichia coli and bovine mitochondria. Also alpha and beta are weakly homologous to each other throughout most of their amino acid sequences, suggesting that they have common functions in catalysis. Related sequences in both alpha and beta and in other enzymes that bind ATP or ADP in catalysis, notably myosin, phosphofructokinase, and adenylate kinase, help to identify regions contributing to an adenine nucleotide binding fold in both ATP synthase subunits.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The catalytic and non-catalytic subunits of the ATP synthase R1 component are paralogs that arose prior to LUCA through an ancient duplication of a RecA family protein (P-loop NTPase) followed by loss of catalytic function in one subunit.

    “The catalytic and non-catalytic subunits comprising the soluble hetero-hexameric R1 component, are paralogs to each other. They arose prior to LUCA through an ancient duplication of a RecA family protein (P-loop NTPase) followed by the loss of the catalytic function in one subunit”

  • There are only two basic ways that cells conserve energy as high energy phosphate bonds: substrate level phosphorylation and chemiosmotic energy harnessing using a rotor-stator ATP synthase.

    “There are only two basic ways that cells conserve energy as high energy phosphate bonds: substrate level phosphorylation (Decker et al., 1970) and chemiosmotic energy harnessing using a rotor-stator ATP synthase (Walker et al., 1982; Walker, 2013).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
