Analysis on sequence and structure of AnEGL. A Amino acid sequence alignment of EGLs. 1KS4, 5GM3, 5M2D, 4H7M, 1OA2, 1H8V, and 1OLQ are the PDB IDs of EGLs, 1KS4: EGL from A. niger, 5GM3: EGL from Aspergillus aculeatus, 5M2D: EGL from Acremonium chrysogenum, 4H7M: EGL from Trichoderma harzianum, 1OA2, 1H8V, and 1OLQ: EGLs from Trichoderma reesei. The residues with 100% homology level are highlighted with yellow. The substrate binding residues and catalytic residues of AnEGL are marked with red solid circles and pentagrams, respectively. B Modeling structure and key residues of AnEGL. The structures of EglA and AnEGL are displayed with light green and light orange, respectively. Key residues of EglA and AnEGL are displayed with green and orange, respectively. C Distribution of key loops involved in substrate binding
