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:0000256|HAMAP-Rule:MF_00798}.
CC -!- SUBUNIT: Oligomer of 11 identical subunits arranged in doughnut-like
CC structure. {ECO:0000256|ARBA:ARBA00011104, ECO:0000256|HAMAP-
CC Rule:MF_00798}.
CC -!- SIMILARITY: Belongs to the MtrB family. {ECO:0000256|ARBA:ARBA00010027,
CC ECO:0000256|HAMAP-Rule:MF_00798}.
