Comparison between the N-terminal domain of PUL and TmCBM41 from structure and sequence analysis.
(a) Structure overlap of the N-terminal domain of PUL (grey) and TmCBM41 (yellow) with carbohydrate-binding sites in stick and the ligand in line. (b) Amino acid sequence alignment of the N-terminal domain of PUL and TmCBM41 with the secondary structures, respectively. The carbohydrate-binding sites were indicated above and below the sequences with red and blue triangles for TmCBM41 and PUL, respectively.
