FunctionFunction

Tryptophan RNA-binding attenuation protein (TRAP) is a tryptophan-activated RNA-binding protein which regulates the expression of the tryptophan biosynthesis genes. TRAP is composed of 11 identical subunits arranged in a symmetrical ring. Down regulation of Trp biosynthesis is observed upon binding of 11 Trp to TRAP.
