Figure 5. Amino acid sequences and organization of the Leishmania donovani complex HASPB repeat region.

Figure 5

Panel A. Comparison of peptide repeats motif sequences found in L. infantum and L. donovani. Panel B. Bar code of peptide motif organization for the k26 repeat region of HASPB in Leishmania donovani complex from different geographic regions of the Old World. Peptides A (bright yellow) −14 amino acid peptides found both in L. donovani and/or L. infantum; Peptides a (banana yellow) −14 amino acid peptides found primarily in L. infantum containing the arginine (R) substitution at position 6; Peptides B (blue) −13 amino acid peptides found in L. donovani. Peptide A3 found in both species was chosen as the reference sequence to which the amino acid sequences of all the other peptides are compared: Single amino acid abbreviations in blue indicates a substitution, in red a deletion, and in black conserved; (−) missing amino acid, (.) conserved amino acid. Peptides numbers from 0–19 have amino acid sequences identical to those reported by Maroof et al. [29]; those with numbers ≥ 20 are new sequences described in this study.
