| Architecture | Bacteria | Pore size and unit- cell volume | Cross- linking (theoretical maximum) | Glycan chain lengths | Muramidase digested maximum PG fragments |
|---|---|---|---|---|---|
| Parallel-Stem | S. aureus | Smallest | 100% | Shortest | oligomers |
| Perpendicular- Stem | E. faecium S. pneumonia | Intermediate | ~70% (model dependent) | Intermediate | tetramers |
| Antiparallel-Stem | E. coli B. subtilis | Largest | 50% | Longest | dimers |
