comments
The C-terminal of this enzyme, which seems to be phosphorylated, is not included in the PDB structure.
According to the literature [4], Cys124, Arg130 and Asp92 are catalytic residues. Asp92 acts as a general acid, to protonate the leaving, phonolic oxgen atom.
As the catalytic domain of this enzyme is homologous to dual specificity protein phosphatase 3 (Swiss-prot;P51452; S00458 in EzCatDB), the catalytic mechanism can be similar to that. In the protein phosphatase 3, Ser131 facilitates the reaction by interacting with the thiol group of Cys124. The corresponding residue, Thr131 also seems to interact with Cys124 in this enzyme structure (PDB; 1d5r).
