Comparison of the substrate distortion in the −1 subsite through structural alignment of RBcel1_E135A monomers A (cyan) and B (yellow) from the structure of RBcel1_E135A in complex with cellotriose (PDB entry 5ljf) and the GH5 β-1,4-glucosidase from P. horikoshii in a Michaelis complex with cellotetraose (pink; PDB entry 3qhn). The subsites are identified from −4 to +2. The residue annotations refer to the numbering in RBcel1_E135A. |
