Abstract

Ribosomes—the primary macromolecular machines responsible for translating the genetic code into proteins—are complexes of precisely folded RNA and proteins. The ways in which their production and assembly are managed by the living cell is of deep biological importance. Here we extend a recent spatially resolved whole‐cell model of ribosome biogenesis in a fixed volume [Earnest et al., Biophys J 2015, 109, 1117–1135] to include the effects of growth, DNA replication, and cell division. All biological processes are described in terms of reaction‐diffusion master equations and solved stochastically using the Lattice Microbes simulation software. In order to determine the replication parameters, we construct and analyze a series of Escherichia coli strains with fluorescently labeled genes distributed evenly throughout their chromosomes. By measuring these cells’ lengths and number of gene copies at the single‐cell level, we could fit a statistical model of the initiation and duration of chromosome replication. We found that for our slow‐growing (120 min doubling time) E. coli cells, replication was initiated 42 min into the cell cycle and completed after an additional 42 min. While simulations of the biogenesis model produce the correct ribosome and mRNA counts over the cell cycle, the kinetic parameters for transcription and degradation are lower than anticipated from a recent analytical time dependent model of in vivo mRNA production. Describing expression in terms of a simple chemical master equation, we show that the discrepancies are due to the lack of nonribosomal genes in the extended biogenesis model which effects the competition of mRNA for ribosome binding, and suggest corrections to parameters to be used in the whole‐cell model when modeling expression of the entire transcriptome. © 2016 Wiley Periodicals, Inc.

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

  • Components of a ribosome biogenesis model developed for slow-growing E. coli have on average 50% sequence identity to genetic information processing genes in JCVI-syn3A.

    “As its components have on average 50% sequence identity to those genetic information processing genes in JCVI-syn3A”

    From Essential metabolism for a minimal cell (2019) · cites this paper as Earnest et al., 2016

    The Introduction describes a ribosome-biogenesis model for slow-growing E. coli, and Section 2.2 identifies its ribosomal components. Our copy does not report a comparison with JCVI-syn3A genes or the claimed average 50% sequence identity; searches for those terms found no supporting passage. (LLM, conf=0.84)

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.
