Abstract

Polyphosphate kinase (PPK) catalyzes the reversible transfer of the terminal phosphate of ATP to form a long-chain polyphosphate (polyP) (Ahn, K., and Kornberg, A. (1990) J. Biol. Chem. 265, 11734-11739). The Escherichia coli gene (ppk) encoding PPK has been cloned, sequenced, and overexpressed (about 100-fold). The gene possesses an open reading frame for 687 amino acids (mass of 80,278 Da). PPK has been purified from overproducing cells after release from attachment to the cell outer membrane; the purified soluble PPK reassociate with cell membrane fractions. About 850 molecules of PPK are found in a wild type cell.

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.
