Figure 2From: Neorickettsia risticii surface-exposed proteins: proteomics identification, recognition by naturally-infected horses, and strain variationsP51 amino acid sequence variations. Amino acids different from N. risticii Illinois, including insertions and deletions are divided by the number of sequences plotted for each amino acid position (# aa diffs). The horizontal axis displays P51 amino acid positions (aa position) including the signal peptide and all detected amino acid insertions (515 aa total). SP, signal peptide. E, external loop; and TM, transmembrane domain are based on the predicted secondary structure [39]. The number of sequences available at each amino acid position on P51 (# seqs) is shown below.Back to article page
