confers_resistance_to_antibiotic erythromycin streptomycin kanamycin A linezolid major facilitator superfamily (MFS) antibiotic efflux pump confers_resistance_to_antibiotic trimethoprim chloramphenicol florfenicol Staphylococcus aureus LmrS A0A3M7YRP9 MFS transporters are secondary active transporters with single-polypeptide chains containing 400-600 amino acids that transport small solutes across the membrane by using electrochemical gradients. LmrS has 14 transmembrane helices and, when expressed in E. coli, is capable of extruding a variety of antibiotics inclinding linezolid, trimethoprim, florfenicol, chlorampheniocol, erythromycin, streptomycin, kanamycin, and fusidic acid.
