The gene

Basic information

  • Locus tag: BSU13300

Phenotypes of a mutant

  • a mgtE mutant has a growth defect on rich media, this can be suppressed by the addition of 25 mM Mg2+, moreover the mutant grows well on minimal medim in the presence of citrate PubMed
  • a mgtE yfjQ mutant does not grow on rich media, this can be suppressed by the addition of 25 mM Mg2+, moreover the mutant grows well on minimal medim in the presence of citrate PubMed
