Phenotypes of a mutant
a ''[protein|search|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|24415722]a ''[protein|search|mgtE] [protein|search|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|24415722] The protein
