Eps-Associated RNA element reconstitute EAR-mediated processive antitermination mechanism "in vitro" or in a Gram-negative heterologous host ("E. coli"), suggesting that additional "B. subtilis"-specific factor(s) may also be required for EAR antitermination. Eps-Associated RNA element The "eps"-Associated RNA element (EAR; also called "epsC" motif) is a conserved RNA motif associated with exopolysaccharide ("eps") or capsule biosynthesis genes in a subset of bacteria classified within the order Bacillales. It was initially discovered in "Bacillus subtilis", located between the second and third gene in the "eps" operon (i.e., between "epsB" and "epsC"). Deletion of the EAR element impairs biofilm formation. The combination of comparative sequence alignments
