CC   -!- FUNCTION: This protein is an aporepressor. When complexed with L-
CC       tryptophan it binds the operator region of the trp operon (5'-
CC       ACTAGT-'3') and prevents the initiation of transcription. The complex
CC       also regulates trp repressor biosynthesis by binding to its regulatory
CC       region (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the TrpR family. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAM87274.1; Type=Erroneous initiation; Evidence={ECO:0000305};
CC       Sequence=AAS63878.1; Type=Erroneous initiation; Evidence={ECO:0000305};
