11. They also contained diaminopimelic acid and the N-acetyl type of peptidoglycan . 12. Peptidoglycan , found in some bacterial cell walls contains some D-amino acids.13. In diderm bacteria, the periplasm contains a thin cell wall composed of peptidoglycan . 14. Type A lantibiotics kill rapidly by pore formation, type B lantibiotics inhibit peptidoglycan biosynthesis. 15. This enzyme participates in d-glutamine and d-glutamate metabolism and peptidoglycan biosynthesis. 16. Bacterial killing is mediated by binding to surface-exposed carbohydrate moieties of bacterial peptidoglycan . 17. This layered structure is called peptidoglycan . 18. This enzyme participates in peptidoglycan biosynthesis. 19. The systematic name of this enzyme class is "'peptidoglycan amidohydrolase " '. 20. REG3 gamma specifically targets Gram-positive bacteria because it binds to their surface peptidoglycan layer.
