Structure of tryptophan RNA-binding attenuation protein complex with Trp (PDB code 2exs). Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image Function Tryptophan RNA-binding attenuation protein (TRAP) or transcription attenuation protein MtrB is a tryptophan-activated RNA-binding protein which regulates the expression of the tryptophan biosynthesis genes. Down regulation of Trp biosynthesis is observed upon binding of 11 tryptophan molecules to TRAP[1]. Structural highlights TRAP is composed of 11 identical subunits arranged in a . The [2]. Water molecules are shown as red spheres.
