Figure 1From: Modulation of inhibitory activity of xylanase - α-amylase inhibitor protein (XAIP): binding studies and crystal structure determination of XAIP- II from Scadoxus multiflorus at 1.2 Å resolutionSequence alignment of XAIP-II (present structure) and XAIP [1]. The secondary structure elements i.e. α-helices (α1 to α8'/α8) and β-strands (β1 to β8) are represented by cylinders and arrows respectively. The regions of polypeptide chain involved in the binding site with xylanase GH11 are highlighted with cyan background and those with α-amylase GH13 are highlighted with green background. The amino acids corresponding to the chitinase active site are indicated in blue colour while cysteine residues are shaded in yellow. The differences in the sequences of XAIP and XAIP-II are indicated in red.Back to article page
