An Acinetobacter baumannii, Zinc-Regulated Peptidase Maintains Cell Wall Integrity during Immune-Mediated Nutrient Sequestration

？ During zinc starvation, A. baumannii expresses a putative peptidase named ZrlA ？ ZrlA is critical for bacterial cell envelope integrity and overcoming Zn limitation ？ Inactivation of zrlA increases antibiotic efficacy in vitro and during infectio
