Phylogenetic and structural difference between two subfamilies of GH29.
a, the phylogenetic analysis of enzymatically characterized GH29 α-l-fucosidases. The tree was constructed using the ClustalW program with a neighbor-joining method (55). b, comparison of the catalytic sites of BiAfcB (D172A/E217A-LNFP II complex; protein in green; ligand in yellow) and TmFuc (Fuc complex; magenta; Protein Data Bank code 1ODU) (stereoview) (44). The numbers of the residues of BiAfcB and TmFuc are labeled in green and magenta, respectively. See also supplemental Figs. S11 and S12.
