unknown subfamily of atypical dual-specificity phosphatases from fungi
This uncharacterized subfamily belongs to the plant and fungi atypical dual-specificity phosphatases (PFA-DSPs) group of atypical DSPs that present in plants, fungi, kinetoplastids, and slime molds. They share structural similarity with atypical- and lipid phosphatase DSPs from mammals. The PFA-DSP group is composed of active as well as inactive phosphatases. This unknown subgroup contains the conserved the CxxxxxR catalytic motif present in active cysteine phosphatases.
Feature 1: catalytic site [active site], 2 residue positions
Conserved feature residue pattern:C R
Evidence:
Comment:the catalytic cysteine initiates a nucleophilic attack on the phosphate group of the substrate, forming a transient phosphoenzyme intermediate and releasing the substrate dephosphorylated; the transition state is stabilized by the arginine present in the catalytic pocket
