EntS(YbdA) overexpression reduces intracellular arabinose, but not xylose, concentration; other compounds were not tested (Koita, 2012). Major Facilitator Superfamily (MFS). Mutations in entS have a hyperlethality phenotype when cells are stressed; EntS is a protein that reduces the lethal effects of stress (Han, 2010). In addition to its role in iron acquisition, enterobactin plays a role in oxidative stress protection and is required to form colonies on M9 minimal media aerobically (Adler, 2014).
