    Phenotypes of a mutant

  • a ''[gene|1986DB3078FBA16D6ACCD70EEAC95C46564D0958|whiA] [gene|8C94C9598A823A8405B3E1FA0124E21D90845B8E|minC]-[gene|37DAD42A391E2FC506225EAF91B8F21629A401DF|minD]'' mutant grows poorly, and the cells are filamentous [Pubmed|24097947]
  • The protein

    Catalyzed reaction/ biological activity

  • The Min system prevents minicell formation adjacent to recently completed division sites by promoting the disassembly of the cytokinetic ring, thereby ensuring that cell division occurs only once per cell cycle [Pubmed|20352045]
  • required for oriC placement during spore development [Pubmed|27059541]
  • Protein family

  • ParA family (with [protein|D6D34E68FB3BAAACB533F98290FD363A5B00B2C6|FlhG] and [protein|5B3DB5A796ACA48390278E60478DFF13D0074A8D|ParA], according to UniProt)
  • Structure

  • [PDB|4V03] (from ''Aquifex aeolicus'', 51% identity) [Pubmed|25500731]
  • [SW|Localization]

  • polar/ septal at the cell membrane [Pubmed|20566861]
  • membrane binding/ polar localization depends on the proton motive force [Pubmed|20566861]
