confers_resistance_to_antibiotic acriflavine puromycin major facilitator superfamily (MFS) antibiotic efflux pump confers_resistance_to_antibiotic MdtNOP sdsRQP antibiotic_resistance ycjRQP MdtNOP MdtNOP is a MFS efflux pump protein found in E. coli. The deletion of mdtP from strain W3110 resulted in increased susceptibility to acriflavin, puromycin, and tetraphenylarsonium chloride. An E. coli mdtN null mutant is more sensitive to sulfur drugs than wild type. ARO:3004101
