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. else 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. end case CC -!- SUBUNIT: Homodimer. CC -!- SUBCELLULAR LOCATION: Cytoplasm. CC -!- SIMILARITY: Belongs to the TrpR family.
