malfunction | a pbgP/pmrC double mutant resembled a pmrA mutant both in its lipid A profile and in its susceptibility to polymyxin B, mutation of the pmrC gene results in lipid A that lacks phosphoethanolamine. The inactivation of both the pmrC and pbgP genes in the polymyxin B-resistant pmrA505 genetic background reduces polymyxin B resistance to the levels of the pmrA null mutant | Salmonella enterica |
metabolism | the PmrA-activated pmrC gene encodes an inner membrane protein that is required for the incorporation of phosphoethanolamine into lipid A and for polymyxin B resistance. The pbg operon and the pmrC genes are solely responsible for PmrA-regulated polymyxin B resistance, but the pmrC gene is dispensable for resistance to Fe3+ | Salmonella enterica |
physiological function | the PmrA/PmrB regulatory system of Salmonella enterica controls the modification of lipid A with aminoarabinose and phosphoethanolamine, the PmrA-dependent modification of lipid A with aminoarabinose and phosphoethanolamine is responsible for PmrA-regulated polymyxin B resistance | Salmonella enterica |
