'''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.
'''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<ref>PMID:14687568</ref>.
