Comparison of Trichoderma spp. Cel7A structures. a Superposition of TatCel7A_CD APO (blue), ThaCel7A_CD (green; PDB code 2YOK), and TreCel7A_CD (gray; PDB code 4C4C). Loop regions are highlighted in red, and cellononaose from 4C4C is shown with white carbon atoms. Sections I–IV, defined by RCA, are marked in yellow, and amino acid residues with high S-scores in TatCel7A are shown as sticks. b Back side of TatCel7A_CD APO structure. c Back side of TreCel7A_CD. In b, c, polar interactions between β-strands are shown as green dashed lines
