THRH_PSEAE Phosphoserine phosphatase that mediates dephosphorylation of phosphoserine in the serine biosynthesis pathway. Also able to dephosphorylate other substrates such as phospho-L(or D)-threonine, with lower activity. Shows phosphoserine:homoserine phosphotransferase activity by transferring the phosphoryl group to homoserine using phosphoserine as the phosphoryl group donor.[1][2]
