  • Localization:
    • during logarithmic growth, MreB forms discrete patches thst move processively along peripheral tracks perpendicular to the cell axis PubMed
    • forms transverse bands as cells enter the stationary phase PubMed
    • close to the inner surface of the cytoplasmic membrane PubMed
    • reports on helical structures formed by MreB PubMed seem to be misinterpretation of data PubMed
    • normal localization depends on the presence of glucolipids, MreB forms irregular clusters in an ugtP mutant PubMed
