    Multiple lineages of Streptomyces produce antimicrobials within passalid beetle galleries across eastern North America

    Rita de Cassia Pessotti et al.
    The widespread occurrence of metabolically active streptomycetes in Odontotaenius disjunctus beetle frass may insulate their galleries against pathogenic fungal invasion through the production of diverse antimicrobial specialized metabolites.

    Evolution of substrate specificity in a retained enzyme driven by gene loss

    Ana Lilia Juárez-Vázquez et al.
    An integrated biochemical and evolutionary analysis shows how enzyme specificity evolves after gene loss during genome decay, implicating relaxation of purifying selection as a driving force for functional divergence.

    A cytoplasmic peptidoglycan amidase homologue controls mycobacterial cell wall synthesis

    Cara C Boutte et al.
    Cell wall biosynthesis in mycobacteria is regulated by an unusual post-translational regulatory system that contributes to antibiotic tolerance during stress.

    Streptomyces exploration is triggered by fungal interactions and volatile signals

    Stephanie E Jones et al.
    Exploratory growth is a newly discovered mode of Streptomyces growth that it is stimulated by fungi, is pH responsive, and can be communicated to other – physically separated – streptomycetes through airborne compounds.

    Ribosomal mutations promote the evolution of antibiotic resistance in a multidrug environment

    James E Gomez et al.
    Mutations in several components of a bacterial ribosome are shown to broadly decrease antibiotic and stress sensitivity, and readily accessible reversion mutations allow these ribosomal mutations to serve as stepping stones to high level antibiotic resistance.

    IRF4 haploinsufficiency in a family with Whipple’s disease

    Antoine Guérin et al.
    Autosomal dominant IRF4 deficiency is the first genetic etiology of Whipple's disease, a very rare chronic condition following a rather common infection by Tropheryma whipplei.

    A microbial clock provides an accurate estimate of the postmortem interval in a mouse model system

    Jessica L Metcalf et al.
    High-throughput sequencing has been used to analyze the microbiome of mouse corpses over a period of 48 days, and to provide an accurate estimate of the time since death.

    A conserved cell division protein directly regulates FtsZ dynamics in filamentous and unicellular actinobacteria

    Félix Ramos-León et al.
    Identification of a novel regulator that directly influences the assembly and function of the cell division machinery in industrially and medically important bacteria.

    Structural and functional insights into the bona fide catalytic state of Streptococcus pyogenes Cas9 HNH nuclease domain

    Zhicheng Zuo et al.
    The catalytic activation of the Cas9 HNH domain involves a unique conformational change in the ββα-metal motif that is collectively driven by the interactions with the metal ions and DNA.
