    The proline-rich antimicrobial peptide Api137 disrupts large ribosomal subunit assembly and induces misfolding by Simon Malte Lauer, Jakob Gasse, Andor Krizsan, Maren Reepmeyer, Thiemo Sprink, Rainer Nikolay, Christian M. T. Spahn, Ralf Hoffmann

    Published 2025-01-01
    “…Separation of cellular extracts derived from cells exposed to Api137 in a sucrose gradient reveals elevated levels of partially assembled and not fully matured precursors of the 50S subunit (pre-50S). High-resolution structures obtained by cryogenic electron microscopy demonstrate that a large proportion of pre-50S states are missing up to five proteins (uL22, bL32, uL29, bL23, and uL16) and have misfolded helices in 23S rRNA domain IV. …”
