"The formation of the terminator requires the trp RNA-binding attenuation protein (TRAP protein) in species of Bacillus and related bacteria. This protein is encoded by the MtrB gene. TRAP protein forms an oligomer of 11 subunits, in the presence of tryptophan this binds to section of RNA containing 11 (G/U)AG repeats. This sequence overlaps the anti-terminator loop, thus TRAP-binding pr… " - Tryptophan rna-binding attenuation protein
