Additional information

The protein

Basic information/ Evolution

  • Catalyzed reaction/ biological activity:
    • forms straight filaments in a heterologous system PubMed
    • polymerizes in the presence of millimolar divalent cations, binds and hydrolyzes GTP and ATP PubMed
    • involved in the organization of ϕ29 DNA replication machinery in peripheral helix-like structures PubMed
  • Protein family: ftsA/mreB family (according to Swiss-Prot)

Extended information on the protein

  • Kinetic information:
  • Domains:
  • Modification:
  • Cofactor(s):
  • Effectors of protein activity:
  • 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

Database entries

  • Structure: 1JCE (from Thermotoga maritima) PubMed
  • KEGG entry: [3]
  • E.C. number:
