Trp RNA-Binding Attenuation Protein: Modifying Symmetry and Stability of a Circular Oligomer

BACKGROUND Subunit number is amongst the most important structural parameters that determine size, symmetry and geometry of a circular protein oligomer. The L-tryptophan biosynthesis regulator, TRAP, present in several Bacilli, is a good model system for investigating determinants of the oligomeric state. A short segment of C-terminal residues defines… CONTINUE READING
