General annotation (Comments)

Function

Catalyzes the reversible conversion of 3-phosphohydroxypyruvate to phosphoserine and of 3-hydroxy-2-oxo-4-phosphonooxybutanoate to phosphohydroxythreonine By similarity. HAMAP MF_00160

Catalytic activity

O-phospho-L-serine + 2-oxoglutarate = 3-phosphonooxypyruvate + L-glutamate. HAMAP MF_00160

4-phosphonooxy-L-threonine + 2-oxoglutarate = (3R)-3-hydroxy-2-oxo-4-phosphonooxybutanoate + L-glutamate. HAMAP MF_00160

Cofactor

Binds 1 pyridoxal phosphate per subunit By similarity. HAMAP MF_00160

Pathway

Amino-acid biosynthesis; L-serine biosynthesis; L-serine from 3-phospho-D-glycerate: step 2/3. HAMAP MF_00160

Cofactor biosynthesis; pyridoxine 5'-phosphate biosynthesis; pyridoxine 5'-phosphate from D-erythrose 4-phosphate: step 3/5. HAMAP MF_00160
