PSPH, 20 µg

Phosphoserine phosphatase is a phosphohydrolase which catalyses the hydrolysis of that metabolizes the conversion of L-phosphoserine to L-serine. It requires a divalent cation such as Mg2+ for maximal activity and the hydrolysis of D- and L-phosphoserine is inhibited by L-, but not D-serine. No protein phosphatase activity has ever been reported for PSP. PSP plays a role in proliferation of embryonic and adult neural progenitors, at least partly through regulation of L-serine production.
