    Phenotypes of a mutant

  • sensitivity to iron, this can be suppressed by low levels of Mn(II) [Pubmed|26261021]
  • reduced genetic competence, can be rescued by the addition of excess zinc [Pubmed|21813502]
  • reduced expression of ''[gene|08CFA2C72931A75532D4289BC1D18A826DE9F9CA|comK]'', control is exerted at the post-transcriptional level and can be rescued by the addition of excess zinc [Pubmed|21813502]

    • The protein

    Catalyzed reaction/ biological activity

  • ATP H2O Zn2 (In) = ADP phosphate Zn2 (Out) (according to Swiss-Prot) P-type zinc-transporting ATPase [Pubmed|12180919]
