a 3D model of the cellulase F1 as predicted using the Swiss-Model server. The GH5-related cellulase module F1_1, residues 44 to 412, was modeled using 3axx.1.A (87.3% amino acid identity) as the template. The GH12-related cellulase modules were modeled using 3vgi.1.A. The first GH12-affiliated module (F1_2; residues 539 to 747, 35.8% amino acid identity) is depicted in red and the second GH12-affiliated module (F1_3; residues 830–1089, 82.7% amino acid identity) is depicted in blue. b Maximum likelihood phylogenetic analysis using amino acid sequences of cellulases identified in this study (in bold) and previously described cellulases derived from members of the domains Eukaryota, Archaea and Bacteria. 1000 iterations were conducted for bootstrap support, and bootstrap values are indicated at each node. Cellulases affiliated with GH9 are highlighted in green, GH12-affiliated sequences are highlighted in blue, GH5-affiliated sequences are highlighted in red and GH1-affiliated sequences are highlighted in yellow
