C. nlpI deletion changes the morphology of EPase-mutant strains. The graph shows the cell width of single and double deletions strains (800 < n < 2000 cells). The box has a medium between 25 and 75%. The whiskers with the upper and lower vertical line indicating the 95 and 5%. The dots are individual points outside the 5 and 95% range. Above the graph are representative images of cells lacking MepS or PBP4 in combination with a deletion of NlpI. The scale bar equals 2 µm. Gene encoding protein legend: nlpI encodes NlpI, dacB encodes PBP4, pbpG encode PBP7, mepM encodes MepM, meps encodes MepS.
