Figure 3

[WY]-x(2)-Y-P-P-L motif. PDB ID: 1ar1, chain A, cytochrome c oxidase. The structural motif corresponding to the [WY]-x(2)-Y-P-P-L sequence motif is highlighted using a ball and stick representation with carbon atoms in green, oxygen atoms in red and nitrogen atoms in blue. The hydrogen bond formed by Trp 164 with heme a3 is also shown as a dashed line.
