    Phenotypes of a mutant

  • increased [protein|D343D2096664A972026D911E7A17A35C7B1CD1C9|DegU]-P formation, resulting in reduced [gene|08CFA2C72931A75532D4289BC1D18A826DE9F9CA|comK] expression and strongly reduced [SW|genetic competence] [pubmed|28800172]
  • no swarming motility on B medium [Pubmed|19202088]
  • not essential for pellicle biofilm formation, but mutant is outcompeted by the wild-type strain when competed during pellicle formation [Pubmed|26122431]
  • few hours delay in pellicle development [Pubmed|26122431]
  • mutant has increased fitness in planktonic culture when competed with the wild-type NCIB3610 strain [Pubmed|26122431]
  • a substitution of Ala233 to Val results in straight flagella [pubmed|28800172]
