    • [SW|Localization]

  • during logarithmic growth, [protein|40829C3632E9DCEB9E1C14A674B4B217F504CFE0|MreBH] forms discrete patches thst move processively along peripheral tracks perpendicular to the cell axis [Pubmed|21636744]
  • forms transverse bands as cells enter the stationary phase [Pubmed|21636744]
  • close to the inner surface of the cytoplasmic membrane [Pubmed|16950129]
  • reports on helical structures formed by MreBH [Pubmed|16950129,20566861] seem to be misinterpretation of data [Pubmed|21636744]
  • normal localization depends on the presence of glucolipids, [protein|A4C8719E06F774A6EB4D79757CC79CF89E453A54|MreB] forms irregular clusters in an ''[gene|7A606B8E952AE8CA4F9A62008BA4B156725BB5B5|ugtP]'' mutant [Pubmed|22362028]
