Phenotypes of a mutant

essential PubMed

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 medium in the presence of citrate (due to the activity of CitM) 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 medium in the presence of citrate (due to the activity of CitM) PubMed
