    A combined quantitative mass spectrometry and electron microscopy analysis of ribosomal 30S subunit assembly in E. coli

    Dipali G Sashital et al.
    Comprehensive structural and compositional characterization of the in vivo 30S ribosomal assembly landscape reveals parallel pathways for 3′-domain formation and a previously unknown role for the assembly factor RimP.

    cryo-EM structures of the E. coli replicative DNA polymerase reveal its dynamic interactions with the DNA sliding clamp, exonuclease and τ

    Rafael Fernandez-Leiro et al.
    Structures of the replicative DNA polymerase Pol IIIα, the DNA sliding clamp, the proofreading exonuclease, and the processivity switch Tau (τ) suggest a mechanism for quick release during lagging strand synthesis.

    Single-molecule FRET unveils induced-fit mechanism for substrate selectivity in flap endonuclease 1

    Fahad Rashid et al.
    Structure specific nucleases that act in DNA replication, repair and recombination actively mold their DNA while transforming their own structure to achieve precise cleavage of their cognate DNA and avoid the deleterious cleavage of noncognate DNA.

    Spatial organization shapes the turnover of a bacterial transcriptome

    Jeffrey R Moffitt et al.
    Transcriptome-scale RNA imaging and lifetime measurements reveal that the E. coli transcriptome is spatially organized and that this organization modulates the post-transcriptional fate of bacterial mRNAs.

    Changes in the genetic requirements for microbial interactions with increasing community complexity

    Manon Morin et al.
    Analysis of the global genetic requirements and gene expression changes in E. coli in the presence of a simple microbiome revealed pairwise and higher-order interactions, and underlying molecular mechanisms.

    Calibration and analysis of genome-based models for microbial ecology

    Stilianos Louca, Michael Doebeli
    A novel computation tool for microbial community modeling predicts the evolution and diversification of E. coli in laboratory evolution experiments and gives insight into the underlying metabolic processes.

    Escherichia coli swimming is robust against variations in flagellar number

    Patrick J Mears et al.
    The swimming behavior of E. coli is surprisingly robust against the natural variations in the number of flagella per cell.

    Evolution of extreme resistance to ionizing radiation via genetic adaptation of DNA repair

    Rose T Byrne et al.
    Experiments on E. coli show that multiple mechanisms contribute to extreme resistance to ionizing radiation in bacteria, with mutations to three genes for DNA repair having a prominent role in one evolved population.

    Coupling of remote alternating-access transport mechanisms for protons and substrates in the multidrug efflux pump AcrB

    Thomas Eicher et al.
    A transport mechanism is uncovered in the major drug-efflux system in E. coli involving two remote alternating-access conformational cycles, which could provide the basis for the development of allosteric inhibitors against multidrug resistance.
