| 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 | 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. |
