1GTF, 1GTN - PubMed Abstract: 
The trp RNA-binding attenuation protein (TRAP) regulates expression of the tryptophan biosynthetic genes in bacilli by binding to the leader region of the nascent trp operon mRNA. When activated by binding tryptophan, the 11-subunit circular TRAP molecule binds to a target sequence consisting of 11 (G/U)AG repeats, separated by two or three variable 'spacer' nucleotides ...
