    Phenotypes of a mutant

  • inactivation of ''[gene|0D555F2AB7DC863E6FF388888308E980514DB719|pchR]'' causes widespread disruption of proteins involved in cellular processes that depend on iron availability, with pleiotropic effects on proteins associated with carbon metabolism, translation, stress response, biosynthesis of cell wall, and sporulation initiation [Pubmed|27542896]
