Figure 1

Structure of Thielavia terrestris β-1,4-endoglucanase TtCel45A (PDB: 5GLY). (a) Divergent stereo cartoon of TtCel45A structure in complex with cellotriose and cellotetraose molecules. (b) Observed electron density for ligands in the active site cleft. The yellow and purple sticks indicate the mutated noncatalytic residues and the catalytic residues, respectively. Hydrogen bonds are represented as black dashed lines. All of the structural diagrams were drawn using PyMOL software.
