Description: To fortify their cytoplasmic membrane and protect it from osmotic rupture, most bacteria surround themselves with a peptidoglycan (PG) exoskeleton. The PG synthases that build this structure are called penicillin-binding proteins (PBPs). Since they are the targets of penicillin and related antibiotics, the structures and in vitro biochemical functions of the PBPs have been extensively studied. However, the in vivo functions of the PBPs and the factors they work with to build the PG meshwork remain poorly understood.
Notes: Keywords: cell envelope, Gram-negative, penicillin-binding proteins, peptidoglycan, peptidoglycan synthesis, peptidoglycan synthetic complex.
