Homology models and primary sequence alignment of Cellulomonas LPMO catalytic modules. ad Cartoon representation of three-dimensional homology models of CflaLPMO10A, CflaLPMO10B, CflaLPMO10C, and CfiLPMO10, respectively, generated using the Phyre2 server with T. fusca LPMO10A as the template structure [81]. The active-site histidine residues are depicted as orange sticks, the three conserved residues of the cellulose-active motif are depicted as yellow sticks, the axial tyrosine or phenylalanine residues are depicted as turquoise or pink sticks, respectively, and the catalytic glutamate or glutamine residues are depicted as teal sticks. Residue numbering corresponds to His-1 in the mature protein sequence. The L2 region is colored red to distinguish it from the immunoglobulin-like β-sandwich core colored in green. e Sequence and secondary structure alignment of Cellulomonas LPMOs compared to T. fusca LPMO10A [73]. The cellulose-active motif is indicated by a green dotted box and the positioning of the conserved residues mentioned in-text are numbered 1–3. The two active site histidine residues are indicated with black star symbols. The red dotted box with star indicates the position of the axial aromatic residue. The position of the catalytic glutamate or glutamine is indicated with a teal star
