Carboxypeptidase activity drives L,D-transpeptidase essentiality during vegetative growth and sporulation in Clostridioides difficile

ABSTRACT In most bacteria, peptidoglycan contains mainly 4-3 crosslinks formed by penicillin-binding proteins (PBPs). However, in the opportunistic pathogen Clostridioides difficile , 70% of the crosslinks are 3-3 crosslinks formed by L,D-transpeptidases (LDTs), and LDTs are esse...
