YnfM may be an arabinose efflux transporter because a ynfM mutant has increased intracellular arabinose, but not xylose; other compounds were not tested (Koita, 2012). A ynfLM clone conferred hypersensitivity to acriflavin, but a ynfM-alone expression clone did not, leading the authors to conclude that overexpression of the putative regulator YnfL was responsible for the Acr-S phenoptype. Major Facilitator Superfamily (MFS). No overexpression drug resistance phenotypes were observed.
