Phenotypes of a mutant
a ''[protein|search|ftsX]'' mutation is synthetically lethal with a ''[protein|search|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]The protein
