Where does the biosynthesis of peptidoglycan take place?

The biosynthesis of bacterial cell wall peptidoglycan is a complex process that involves enzyme reactions that take place in the cytoplasm (synthesis of the nucleotide precursors) and on the inner side (synthesis of lipid-linked intermediates) and outer side (polymerization reactions) of the cytoplasmic membrane.

How is the monomer of peptidoglycan assembled?

In the first step, the monomer unit is assembled by a sequence of reactions in the cytoplasm and at the inner side of the cytoplasmic membrane leading to the lipid II intermediate.
