trimethoprim resistant dihydrofolate reductase dfr [AMR Gene Family]

Accession ARO:3001218
DefinitionAlternative dihydropteroate synthase dfr present on plasmids produces alternate proteins that are less sensitive to trimethoprim from inhibiting its role in folate synthesis, thus conferring trimethoprim resistance.
