The P25 Ookinete Surface Proteins: Homology Modeling and Phylogenetic Relationships
Figure 8
(a) Amino acid composition analysis of the residues of the eight P25 members studied and their comparison with the template protein Pvs25. Groups taken for this analysis are given on the -axis, whereas the percentage of the residues is given on the -axis. Amino acid groups taken according to are aliphatic (G, A, V, L, and I), sulphur containing (C and M), aromatic (F, W, and Y), neutral (S, T, Q, and N), positively charged (K and R), negatively charged residues (D and E), and proline (P). P25 sequences represent almost similar amino acid composition among the members. ((b)-(c)) Amino acid composition analysis of negatively (D and E) and positively charged (K, R, and H) residues of the eight P25 members studied and their comparison with the template protein Pvs25. (b) represents the percentage amino acid composition comparison for individual positively and negatively charged amino acids of studied P25 proteins and Pvs25 protein whereas (c) represents group-wise amino acid composition comparison of P25 proteins, and template Pvs25. Groups taken for this analysis were according to Koolman et al., negatively charged/acidic (D and E), and positively charged/basic (K, R, and H). P25 sequences represent almost similar amino acid composition of positively charged residues in group-wise presentation (b). Percentage of individual amino acids differs significantly among the members.
