Figure 1.

Model of GRW27stamAELL33H. The position of the stammer relative to the metal site (Left) and looking from the N-termini of the 3SCC (Right). The model was created by inserting the stammer (residues 91–93) of ORF1p CCD (6FIA[17]) into the 5KB0[13b] structure of GRCSL16C30H to create a chimeric structural model (complete details including colored representations are provided in the SI). The sidechains of Ala27 and Glu28 of the stammer and the zinc-coordinating His33 are shown as shaded sticks.
