PBP1A and LdtJ transpeptidase activities are crucial for cell envelope homeostasis and counteract the selection of colistin resistance in Acinetobacter baumannii
ABSTRACT The multilayered cell envelope of Acinetobacter baumannii is an essential structure that maintains cellular integrity and protects the bacterial cell against external stresses and antibiotics. It consists of an inner membrane, a thin peptidoglycan (PG) layer, and an asymmetric outer membrane (OM) enriched in l...
