Lipid A deacylase PagL, which detoxifies endotoxin, is latent in Salmonella enterica. This study determined the biological significance of this latency. PagL latency was beneficial for bacteria in producing a robust permeation barrier through lipid A modifications under host-mimetic conditions that induced the modification enzymes, including PagL.
脂质 A 脱酰酶 PagL 能够解毒内毒素,潜伏在沙门氏菌中。本研究确定了这种潜伏的生物学意义。在诱导包括 PagL 在内的修饰酶的宿主模拟条件下,PagL 潜伏有利于细菌通过脂质 A 修饰产生强大的渗透屏障。
