Fig. 6From: Extensive structural variation in the Bowman-Birk inhibitor family in common wheat (Triticum aestivum L.)Alignment of the conserved Cys-rich domains of common wheat BBI proteins. a Alignment of common wheat BBI proteins falling into group MI-I; b MI-II group; c MI-IV group; and d BBI proteins that cannot be classified into an existing group. The Cys residues are highlighted in red with their corresponding position indicated above each alignment. The blue arrow underneath the domain sequences highlight the P1 and P1’ positionsBack to article page
