In enzymology, a phosphoserine phosphatase (EC 3.1.3.3) is an enzyme that catalyzes the following chemical reaction:

O-phospho-L(or D)-serine + H2O L(or D)-serine + phosphate ion

This enzyme belongs to the family of hydrolases, specifically those acting on phosphoric monoester bonds. The systematic name of this enzyme class is O-phosphoserine phosphohydrolase. This enzyme participates in glycine, serine and threonine metabolism.

Structural studies[edit]

As of late 2007, 12 structures have been solved for this class of enzymes, with PDB accession codes 1F5S, 1J97, 1L7M, 1L7N, 1L7O, 1L7P, 1L8L, 1L8O, 1NNL, 2J6Y, 2J6Z, and 2J70.
