Domain structures of FPU-7 chitinases. The bars and numbers indicate positions of amino acid sequences. Protein sequence was analyzed by using the Pfam server, and the locations of the following domains are indicated: signal peptide (black boxes), GH-18 catalytic domains (GH-18; Pfam ID, PF00704), carbohydrate-binding module (CBM-5/12; Pfam ID, PF02839), chitinase A N-terminal domain (ChitinaseA_N; Pfam ID, PF08329), fibronectin type III domain (hatched boxes; Pfam ID, PF00041), and SLH domains (boxes with horizontal lines; Pfam ID, PF00395).
