CC   -!- FUNCTION: This protein is an aporepressor. When complexed with L-
CC       tryptophan it binds the operator region of the trp operon and prevents
CC       the initiation of transcription. {ECO:0000255|HAMAP-Rule:MF_00475}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00475}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00475}.
CC   -!- SIMILARITY: Belongs to the TrpR family. {ECO:0000255|HAMAP-
CC       Rule:MF_00475}.
