• Structural insights into the mechanism of adaptive ribosomal modification by Pseudomonas RimK

    Abstract
    Bacteria are equipped with a diverse set of regulatory tools that allow them to quickly adapt to their environment. The RimK system allows for Pseudomonas spp. to adapt through post-transcriptional regulation by altering the ribosomal subunit RpsF. RimK is found in a wide range of bacteria with a conserved amino acid sequence, however the genetic context and the role of this protein is highly diverse. By solving and comparing the structures of RimK homologues from two related but functionally divergent systems, we uncovered key structural differences that likely contribute to the...
