Names

Trp_attenuator

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

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 (By similarity).

SUBUNIT: Oligomer of 11 identical subunits arranged in doughnut-like structure (By similarity).

SIMILARITY: Belongs to the mtrB family.
