Vibrio cholerae mutants lacking lytic transglycosylases MltC and RlpA are defective for daughter cell separation. Our results suggest that lytic transglycosylases at the division septum serve as a back‐up mechanism to cleave peptidoglycan strands that cannot be cleared by highly‐regulated amidase activity and to clear peptidoglycan debris that may block the completion of outer‐membrane...
