Design Notes

The mutation sites locate in substrate binding site, subsite II where three MHET moieties are bound through hydrophobic interaction. In TfCut2, Histidine 169 residues and Isoleucine 253 are located at the corresponding positions of Trpytophan 159 and Serine 245 in subsite II of IsPETase. The resulting double mutant makes the substrate binding site, substrate II more cutinase-like and increases the hydrophobic property of the enzyme.
