This structure supersedes the now removed PDB entry 1p6z. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance. Method: X-ray diffraction, Resolution 1.6693Å Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function TRPR_ECOLI This protein is an aporepressor. When complexed with L-tryptophan it binds the operator region of the trp operon (5'-ACTAGT-'3') and prevents the initiation of transcription. The complex also regulates trp repressor biosynthesis by binding to its regulatory region.
