    Phenotypes of a mutant

  • essential [Pubmed|12682299]
  • a constitutively active form of [protein|7F340423A34CE40D1F1AA8D373F7C4B859A6496D|WalR] ([protein|7F340423A34CE40D1F1AA8D373F7C4B859A6496D|WalR]-R204C) results in constitutive expression of the [protein|7F340423A34CE40D1F1AA8D373F7C4B859A6496D|WalR] regulon, and in combination with a ''[gene|DB09F1C36257F511A84A083967A25A9D46744D14|sepF]'' mutation to the formation of cell wall-less L-forms [Pubmed|22122227]
