Abstract/OtherAbstract:
Autolysins are exoenzymes formed by bacteria to aid in wall expansion and in cell division. For the Gram-positive rod, these enzymes function predominately on the periphery of the wall. As they destroy their substrate they rebind to peptidoglycan when the cell density is high. Only then is the concentration of autolysins high enough on the external surface to favor cell division and prevent the formation of chains of cells (filaments). It is suggesting that circumstance is important for the kinetics of turnover of the wall and the splitting of the septum.
