Catalyzes the last step in the biosynthesis of serine from carbohydrates. The reaction mechanism proceeds via the formation of a phosphoryl-enzyme intermediates. Defects in PSPH are the cause of phosphoserine phosphatase deficiency (PSPHD)[MIM:614023]. A disorder that results in pre- and postnatal growth retardation, moderate psychomotor retardation and facial features suggestive of Williams syndrome. Belongs to the SerB family.
