Figure 6

Tertiary structure of E. coli EF-Tu (PDB ID: 1EFC) [57], which has two identical polymer chains (A and B). The covarion residues are mapped on the A chain (the top polymer). The red arrow points to the purple strip of a loop region of 10 nearly consecutive covarion sites (sites 37, 38, 40 - 46, 48 in 1EFC), which corresponds to sites 31, 32, 34 - 40, 42 on the EF alignment listed in Figure 5. The loop region is connected to the two helices, one at either end.
