    The guide sRNA sequence determines the activity level of box C/D RNPs

    Andrea Graziadei et al.
    Integrative structural biology reveals a conformational equilibrium in the Box C/D methylation enzyme that regulates the extent of site-specific 2'-O-rRNA methylation in dependence of the RNA sequence.

    Translational initiation in E. coli occurs at the correct sites genome-wide in the absence of mRNA-rRNA base-pairing

    Kazuki Saito et al.
    E. coli ribosomes incapable of base-pairing with the Shine-Dalgarno sequence are still selective for annotated start sites, indicating these sites are hard-wired for initiation by other mRNA features.

    Nucleophosmin integrates within the nucleolus via multi-modal interactions with proteins displaying R-rich linear motifs and rRNA

    Diana M Mitrea et al.
    Nucleolar protein localization involves the phase separation within the nucleolar matrix via three types of multivalent features: acidic tracts, nucleic acid binding domains and arginine-rich low complexity sequences.

    Genomic adaptations in information processing underpin trophic strategy in a whole-ecosystem nutrient enrichment experiment

    Jordan G Okie et al.
    Trait-based metagenomic analysis of an ecosystem fertilization experiment shows that genomic traits that affect the costs and rates of biochemical information-processing mediate community assembly.

    RNA structures that resist degradation by Xrn1 produce a pathogenic Dengue virus RNA

    Erich G Chapman et al.
    The Dengue virus contains discretely folded RNA structures that confer the ability to resist a powerful host cell enzyme and produce a disease-inducing noncoding RNA.

    A RanGTP-independent mechanism allows ribosomal protein nuclear import for ribosome assembly

    Sabina Schütz et al.
    The Tsr2 carrier protein connects the nuclear import machinery with the ribosome assembly pathway.

    Consistent and correctable bias in metagenomic sequencing experiments

    Michael R McLaren et al.
    A mathematical model of bias in marker-gene and metagenomic sequencing measurements explains systematic errors in defined mixtures of microbial species, and enables quantitative and reproducible investigation of biological communities.

    Structural insights into the mechanism of the DEAH-box RNA helicase Prp43

    Marcel J Tauchert et al.
    The structural and functional analysis of the ATP-dependent RNA helicase Prp43 provides insights into the mechanisms of RNA binding and translocation, which could serve as paradigm for all DEAH-box proteins.

    Cryo-EM structure of a late pre-40S ribosomal subunit from Saccharomyces cerevisiae

    André Heuer et al.
    Near atomic resolution of late 40S ribosomal subunit assembly by cryo-EM reveals immature rRNA active sites stabilized by biogenesis factors.

    Structural basis for AcrVA4 inhibition of specific CRISPR-Cas12a

    Gavin J Knott et al.
    An ancestral helical bundle governs whether the crRNA-processing nuclease of CRISPR-Cas12a is exploited by a phage-encoded allosteric anti-CRISPR.
