Phenotypes of a mutant

• a ''[gene|E22D0F0AC56DC95AFC02E7F55FCD5FAA44B6B490|ftsX]'' mutation is synthetically lethal with a ''[gene|321F248C22D7283C0F3323F1F4069E36F8D7FE6C|lytE]'' mutation (due to a lack of autolysin activity) [Pubmed|23869552,23855774]
• shorter, fatter cells, this can be rescued by addition of Mg(2+) [Pubmed|23869552,23855774]
• reduced growth rate, especially at low Mg(2+) concentrations [Pubmed|23869552]
• loss of genetic competence [pubmed|29553055]
