Tryptophan RNA-binding attenuation protein

Function Tryptophan RNA-binding attenuation protein (TRAP) 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 Trp to TRAP. Structural highlights TRAP is composed of 11 identical subunits arranged in a symmetrical ring. Tryptophan is bound to TRAP by mostly non-polar residues.
