Figure 2. Schematic diagram showing the location of binding sites in the β-sandwich Type B CBMs.
This Figure was produced by overlapping the C-α carbons for all of the β-sandwich Type B CBMs for which ligand bound complexes were available. Only the ribbon structure of the family 4 CBM from the N-terminus of Cel9B from Cellulomonas fimi is shown as a representative β-sandwich Type B CBM. Oligosaccharide ligands are shown in ‘liquorice’ representation and coloured as follows: cyan, cellotetraose from CcCBM17 (PDB code 1J84 [60]); blue, laminariohexaose from TmCBM4-2 (PDB code 1GUI [68]); pink, cellopentaose from CfCBM4-2 (PDB code 1GU3 [68]); marine/aqua, xylotriose from CsCBM6-3 (PDB code 1NAE [61]); orange, cellohexaose from PeCBM29-2 (PDB code 1GWM [69]); green, mannopentaose from TmCBM27 (PDB code 1OF4 [73]); purple, xylopentaose from CjCBM15 (PDB code 1GNY [67]).
