Screening for synthetic lethal mutants in Escherichia coli and identification of EnvC (YibP) as a periplasmic septal ring factor with murein hydrolase activity.


Bacterial cytokinesis is driven by the septal ring apparatus, the assembly of which in Escherichia coli is directed to mid-cell by the Min system. Despite suffering aberrant divisions at the poles, cells lacking the minCDE operon (Min(-)) have an almost normal growth rate. We developed a generally applicable screening method for synthetic lethality in E… (More)
