FIGURE 2.

Trigger RNA hairpin-coat protein dimer interaction. The asymmetric A/B dimer of two coat proteins is shown in blue and green ribbons. The RNA helix stretches across the β-sheet dimer interface. Two adenines that make important hydrogen bonds with each coat protein are shown in bright pink. The adenine in the 3′ position of the hairpin hydrogen bonds with lysine, threonine, and serine amino acids on the blue dimer. The single bulge adenine interacts with lysine, threonine, and serine amino acids on the green dimer.
