SOLUTION STRUCTURE OF E.coli POLYMYXIN RESISTANCE PROTEIN PmrD

In Gram-negative bacteria,a two-component system named PmrA/PmrB system is found to be responsible for the resistance to the cationic peptide antibiotic polymyxin B[1].In Salmonella enterica,there are two pathways to activate the PmrA/PmrB system.Fe~(3+)In Gram-negative bacteria,a two-component system named PmrA/PmrB system is found to be responsible for the resistance to the cationic peptide antibiotic polymyxin B[1].In Salmonella enterica,there are two pathways to activate the PmrA/PmrB system.Fe~(3+)China Association for Instrumental Analysis
