RL   Submitted (JUN-2009) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: Required for transcription attenuation control in the Trp
CC       operon. This trans-acting factor seems to recognize a 10 bases
CC       nucleotide sequence in the Trp leader transcript causing transcription
CC       termination. Binds the leader RNA only in presence of L-tryptophan.
CC       {ECO:0000255|HAMAP-Rule:MF_00798}.
CC   -!- SUBUNIT: Oligomer of 11 identical subunits arranged in doughnut-like
CC       structure. {ECO:0000255|HAMAP-Rule:MF_00798}.
CC   -!- SIMILARITY: Belongs to the MtrB family. {ECO:0000255|HAMAP-
CC       Rule:MF_00798}.
