Stereo ribbon representation of PAN and CBM1-PAN1 from CBEL bound to cellulose. A) Comparison of the ribbon diagrams of domains HGF_PAN (left) and CBEL_PAN1-1 (right). The α-helix (α1) and strands of b-sheets (β1-β2) are numbered from the N- to the C- terminus. The cysteine residues linked by disulphide bonds (dashed lines) are displayed in black ball-and-sticks and numbered. B) The cysteine residues linked by disulphide bonds (dashed lines) are displayed in black ball-and-sticks and numbered. The extended strand of β-sheet interconnecting the two domains is indicated by an asterisk. The aromatic residues of CBM1 interacting with cellulose are in grey ball-and-sticks and labelled. The figures are drawn using Molscript[67], and Raster3D[68].
