Fig. 1

Structure of the PirXI active site and design of mutant library LibM1. The figure shows the active site structure of PirXI with xylose (yellow) and Mg2+ ions (green spheres) bound (PDB: 5NH7). The target residues (orange) are located near the active site. The catalytic metal (M2) can occupy two positions (M2a and M2b). W307′ is a residue from a neighboring subunit
