Figure 4 The I/YxGG/A motif. (A) The primer and template strands from the ternary complex are shown as yellow and gray sticks, respectively. The template strand and the residues of the I/YxGG/A motif are shown as spheres. (B) The two distinct populations of Y226 are shown in sticks based on a superposition of the palm subdomain. The residues are colored by crystal structure.
