New Cell Division Protein in Escherichia coli Bacterial cell division is accomplished by proteins with two defining characteristics: they localize to the midcell, and their mutants stall division. Jorgenson and Young (e00046-18) present evidence for a new cell division protein in Escherichia coli, YtfB. YtfB is recruited to midcell during the early stages of septation, and a ytfB mutant exacerbates the division defect of cells lacking DedD, a separate division protein. Although a LysM-like OapA domain derived from YtfB binds to peptidoglycan and directs fusion proteins to the wall at midcell, the domain is not necessary for localizing full-length YtfB.
