Figure 1. Structure and topology of PpAlgJ_75–370.

(A) Cartoon representation of PpAlgJ_75–370 with secondary structural elements labelled (α: α-helix; β: β-strand; and t: 3₁₀ helix). Residues at discontinuous points in the structure due to poor observed electron density are labelled and coloured red. The N- and C-termini of the protein are labelled N and C, respectively, and the terminal residue is coloured red. (B) Topology model of the PpAlgJ_75–370 structure with secondary structural elements and termini labelled as in panel (A).
