Design Notes

The mutation sites locate in substrate binding site, subsite II where three MHET moieties are bound through hydrophobic interaction. In TfCut2, Isoleucine 253 residues are located at the corresponding positions of Serine 245 in subsite II of IsPETase. The resulting double mutant makes the substrate binding site, subunit II more cutinase-like and increases the hydrophobic property of the enzyme.
