RT and its unexpected adaptive capabilities to extreme environments.";
RL Nucleic Acids Res. 30:3927-3935(2002).
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 (By
CC similarity). {ECO:0000250}.
CC -!- SUBUNIT: Oligomer of 11 identical subunits arranged in doughnut-like
CC structure. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the MtrB family. {ECO:0000305}.
