FIGURE 1.

Overall structure of AlgX. A, schematic representation of AlgX with secondary structure elements labeled as follows: α-helix (α), β-strand (β), 3₁₀ helix (t). The N-terminal α/β/α and C-terminal CBM domains are represented in blue and red, respectively. The two disulfide bonds present in the structure are colored in yellow. The dashed lines represent residues that cannot be built or modeled due to poor quality electron density. N and C, N and C termini of the protein. B, topology representation of AlgX with the secondary structural elements labeled and colored as in A.
