    Phenotypes of a mutant

  • essential [Pubmed|12682299]
  • the gene can be deleted, but the mutant acquires suppressors in ''[gene|2D4E3D6C3634C3F42A4517D5C1A8F4F48CAFF3A6|dtrR]'' to allow expression of ''[gene|1968743631A20739B5DA8B489CB1E7E42F3B93E3|tyrZ]'' [Pubmed|25733610]
  • a ''[gene|EEB0CF0AF0707AC1161F150708F7EDDB749B3C42|tyrS] [gene|1968743631A20739B5DA8B489CB1E7E42F3B93E3|tyrZ]'' double mutant is not viable [Pubmed|25733610]
