Protein
Phosphoserine phosphatase, chloroplastic
Organism
Arabidopsis thaliana
Function
Catalyzes the last step in the plastidial phosphorylated pathway of serine biosynthesis (PPSB). The reaction mechanism proceeds via the formation of a phosphoryl-enzyme intermediates. Required for embryo, pollen and root development. May be required preferentially for serine biosynthesis in non-photosynthetic tissues.
Similarity
Belongs to the HAD-like hydrolase superfamily. SerB family.
