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
