Protein Name: Phosphoserine aminotransferase

UniprotKB/SwissProt ID: Q99K85 (Q99K85)

Gene Name: Psat1

Organism: Mus musculus (Mouse)

Function: Involved in L-serine biosynthesis via the phosphorylated pathway, a three-step pathway converting the glycolytic intermediate 3-phospho-D-glycerate into L-serine. Catalyzes the second step, that is the pyridoxal 5'-phosphate-dependent transamination of 3-phosphohydroxypyruvate and L-glutamate to O-phosphoserine (OPS) and alpha-ketoglutarate
