Abstract

enabled us to integrate and cross-evaluate a massive, heterogeneous dataset based on measurements reported by various groups over decades. We identified inconsistencies with functional consequences across the data, including that the total output of the ribosomes and RNA polymerases described by data are not sufficient for a cell to reproduce measured doubling times, that measured metabolic parameters are neither fully compatible with each other nor with overall growth, and that essential proteins are absent during the cell cycle-and the cell is robust to this absence. Finally, considering these data as a whole leads to successful predictions of new experimental outcomes, in this case protein half-lives.

  • No one organism has a complete set of experimentally determined kinetic parameters, chemical composition, and physical characteristics, so the model presented here, as well as other whole-cell models, has depended on the transferability of quantities among related organisms.

  • The liponucleotide synthase cdsA/0304 catalyzing reaction DASYN was identified as a choke point in phospholipid biosynthesis, in agreement with a recent whole-cell model of E. coli.

    “The liponucleotide synthase cdsA/0304 catalyzing reaction DASYN (Figure S2) that adds CDP to a phospholipid precursor (phosphatidic acid, PA) was identified as a “choke point” in the phoshpolipid biosynthesis, in agreement with a recent whole-cell model of E. coli (Macklin et al., 2020).”

  • Well-stirred simulations can take as little as a few hours per cell cycle and can simulate multiple cells in parallel.

    “Well-stirred simulations can take as little as a few hours per cell cycle and can simulate multiple cells in parallel.1”

    From Bringing the genetically minimal cell to life on a computer in 4D (2026) · cites this paper as [4]

    The paper describes simulations of E. coli cell cycles, but our copy does not state that well-stirred simulations take a few hours of computing time per cycle or that multiple cells can be simulated in parallel. The reported 125-minute doubling time is a simulated biological outcome, not simulation runtime. Searches for “well-stirred,” “parallel,” “hours,” and computational runtime did not establish the claim. (LLM, conf=0.78)

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.
