Figure 4From: Plant protein peptidase inhibitors: an evolutionary overview based on comparative genomicsFeatures of I4 Serpin peptidase inhibitors. (A) Three-dimensional structure of a typical I4 inhibitor (3LE2). Red, α-helices; yellow, β-sheets. (B) Schematic PhyML phylogenetic tree using the selected Serpin sequences from the different plant species. Coloured triangles show clade-specific gene proliferations.Back to article page
