Figure 3From: Plant protein peptidase inhibitors: an evolutionary overview based on comparative genomicsFeatures of I3 Kunitz-P peptidase inhibitors. (A) Three-dimensional structure of a typical I3 inhibitor (1AVU). Cysteines are highlighted as balls and sticks and coloured in CPK. Yellow, β-sheets. (B) Schematic PhyML phylogenetic tree using the selected Kunitz-P sequences from the different plant species. Coloured triangles show clade-specific gene proliferations.Back to article page
