Identifier, protein and gene names [?]

Identifier
MTRB
Protein name
RecName: Full=Transcription attenuation protein MtrB;
AltName: Full=Trp RNA-binding attenuation protein;
Short=TRAP;
AltName: Full=Tryptophan RNA-binding attenuator protein;
Gene name
mtrB

Comments [?]

Function Required for transcription attenuation control in the Trp operon. This trans-acting factor seems to recognize a 10 bases nucleotide sequence in the Trp leader transcript causing transcription termination. Binds the leader RNA only in presence of L-tryptophan.
Subunit Oligomer of 11 identical subunits arranged in doughnut-like structure.
Similarity Belongs to the MtrB family.
