    Protein Summary

    TM1030 is a TetR like transcription repressor. The  structure presented here describes the ligand-bound form of TM1030[Ref]. MCSG, independently determined the  structure of apo-TM1030[Ref]. A structure superposition of apo and ligand bound forms, reveals a dramatic conformational change upon ligand binding.


    Ligand Summary

    There are two UNLs present within the ligand binding pocket of each TM1030 monomer. Based on the shape of the electron density, it is likely a heptaethelene glycol.
