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. {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}.
