Specific Role Of Two NlpC/P60 Endopeptidases In Cell Division And Membrane Vesicle Formation In Deinococcus radiodurans
The bacterial cell wall is composed of peptidoglycan (PG), a sugar polymer cross-linked by short peptide stems. PG determines cell morphology and protects it from environmental stresses.
