PSAT1, also known as phosphoserine aminotransferase, catalyses the conversion of 3-phosphohydroxypyruvate into 3-phosphoserine which is dephosphorylated subsequently by phosphoserine phosphatase to form L-serine. Source: Recombinant protein corresponding to aa1-370 of human PSAT1, fused to His-tag at N-terminal expressed in E. coli.
