    Phenotypes of a mutant

  • loss of swimming and swarming motility [Pubmed|24296669]
  • mucoid phenotype due to the [protein|D343D2096664A972026D911E7A17A35C7B1CD1C9|DegU]-P activated overexpression of the ''[gene|86C05126ADBA22BB1771B1FA3D214B2E7A36311E|capB]-[gene|D66994D077D1382B88FF65075E44C2A31089548F|capC]-[gene|A696434A086A428D411CAF45B37CD8F82AC2503F|capA]-[gene|6B61DCE8D27776EBF942621D3AE90F410FD13F37|capE]'' operon and resulting overproduction of poly-gamma-glutamate [Pubmed|24296669]
  • not essential for pellicle biofilm formation, but mutant is outcompeted by the wild-type strain when competed during pellicle formation [Pubmed|26122431]
