Ecdysteroid-phosphate phosphatase

Ecdysteroid-phosphate Phosphatase is the first structure of a steroid phosphate phosphotase containing alpha beta folds common to members of the two histidine (2H)-Phosphatase superfamily with strong homology to the Suppressor of T-cell receptor signaling-1 (Sts-1 PGM) protein. The putative EPPase PGM active site contains signature residues shared by 2H-phosphatase enzymes, including a conserved histidine (His80) that acts as a nucleophile during catalysis.
