Figure 9From: Plant protein peptidase inhibitors: an evolutionary overview based on comparative genomicsFeatures of I25 Cystatin peptidase inhibitors. (A) Three-dimensional structure of a typical I25 inhibitor (1EQK). Red, α-helix; yellow, β-sheets. (B) Schematic PhyML phylogenetic tree using the selected Cystatin sequences from the different plant species. Coloured triangles show clade-specific gene proliferations.Back to article page
