Schematic representation of Pb INP and its repetitive amino acid sequence. A) Each green or orange box represents one 16-aa repeat within the repetitive central domain. The non-repetitive N- and C-terminal domains are indicated by white rectangles. Boxes coloured orange are the eight repeats modelled in this study. B) WEBLOGO plot [41] of the 64 16-aa repeats of Pb INP. Hydrophobic residues are coloured black, acidic residues red, basic residues blue. Other residues are coloured green or purple. C) The amino acid sequence of Pb INP residues 217-265 is shown. The consensus amino acid sequence of the 3 × 16-aa block is indicated below in italics. Putative β-strands are underlined while x represents any amino acid.
