    Heterogeneous absorption of antimicrobial peptide LL37 in Escherichia coli cells enhances population survivability

    Mehdi Snoussi et al.
    A rapid absorption and retention of antimicrobial peptides by dead Escherichia coli cells can increase the survivability of the cell population in a "cooperative" fashion.

    TAPBPR alters MHC class I peptide presentation by functioning as a peptide exchange catalyst

    Clemens Hermann et al.
    We reveal TAPBPR is a peptide exchange catalyst which restricts the peptide repertoire presented by MHC I on cells, a finding which has important implications for all aspects of immune recognition.

    Method development and characterisation of the low-molecular-weight peptidome of human wound fluids

    Mariena JA van der Plas et al.
    Peptidomics method development and analysis of qualitative differences of peptide patterns in human wound fluids provide potential biomarkers for wound healing and infection.

    Luqin-like RYamide peptides regulate food-evoked responses in C. elegans

    Hayao Ohno et al.
    Identification and functional characterization of C. elegans luqin-like arginine-tyrosine-NH2 (RYamide) peptides reveal their critical role in feeding-related processes.

    Genome-wide effects of the antimicrobial peptide apidaecin on translation termination in bacteria

    Kyle Mangano et al.
    Inhibition of bacterial protein synthesis by an antimicrobial peptide apidaecin triggers translation arrest at the stop codons, ribosome queuing and pervasive stop codon readthrough.

    Structural basis of ribosomal peptide macrocyclization in plants

    Joel Haywood et al.
    The first crystal structure of an active plant asparaginyl endopeptidase reveals a tetrahedral intermediate state in its active site, which may help to explain why these enzymes have been independently recruited to perform peptide macrocyclization.

    Expression levels of MHC class I molecules are inversely correlated with promiscuity of peptide binding

    Paul E Chappell et al.
    The number of different peptides presented by major histocompatibility complex class I molecules to the immune system's T lymphocytes is inversely correlated with cell surface expression and is strongly associated with the response to infectious disease.

    Quantitative mapping of protein-peptide affinity landscapes using spectrally encoded beads

    Huy Quoc Nguyen et al.
    A novel high-throughput method for measuring many weak protein-peptide affinities simultaneously reveals how calcineurin, a human phosphatase essential for the immune response, recognizes its peptide substrates.

    A vocabulary of ancient peptides at the origin of folded proteins

    Vikram Alva et al.
    A comparative study of modern proteins identifies 40 fragments that may represent the observable remnants of a primordial RNA-peptide world.

    Drosophila neprilysins control insulin signaling and food intake via cleavage of regulatory peptides

    Benjamin Hallier et al.
    The catalytic activity of a Drosophila neprilysin is critical to proper insulin expression and food intake by regulating homeostasis of distinct signaling peptides.
