    Functional metagenomics-guided discovery of potent Cas9 inhibitors in the human microbiome

    Kevin J Forsberg et al.
    A high-throughput, activity-based selection identifies many phage-derived inhibitors of Cas9 from human fecal and oral metagenomes, with at least one inhibitor acting via a novel mechanism.

    Control of cyclic oligoadenylate synthesis in a type III CRISPR system

    Christophe Rouillon et al.
    Generation of the anti-viral second messenger cyclic oligoadenylate by type III CRISPR systems is tightly controlled in response to viral RNA load and sequence.
  1. Research: Sci-Hub provides access to nearly all scholarly literature

    Daniel S Himmelstein et al.
