small multidrug resistance (SMR) antibiotic efflux pump [AMR Gene Family]

Accession ARO:0010003
Synonym(s)SMR type drug efflux
DefinitionDirected pumping of antibiotic out of a cell to confer resistance. Small multidrug resistance (SMR) proteins are a relatively small family of transporters, restricted to prokaryotic cells. They are also the smallest multidrug transporters, with only four transmembrane alpha-helices and no significant extramembrane domain.
