Protein

Transcription attenuation protein MtrB

Gene

mtrB

Organism
Bacillus subtilis (strain 168)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

Functioni

Required for transcription attenuation control in the trp operon. This trans-acting factor binds to trinucleotide repeats (GAG or UAG) located in the trp leader transcript causing transcription termination. Binds the leader RNA only in presence of L-tryptophan.2 Publications
