Function
function
Catalyzes the reversible conversion of 3-phosphohydroxypyruvate to phosphoserine and of 3-hydroxy-2-oxo-4-phosphonooxybutanoate to phosphohydroxythreonine.
Catalytic activity
- 2-oxoglutarate + O-phospho-L-serine = 3-phosphooxypyruvate + L-glutamate
Cofactor
Note: Binds 1 pyridoxal phosphate per subunit.
Pathway
Amino-acid biosynthesis; L-serine biosynthesis; L-serine from 3-phospho-D-glycerate: step 2/3.
Cofactor biosynthesis; pyridoxine 5'-phosphate biosynthesis; pyridoxine 5'-phosphate from D-erythrose 4-phosphate: step 3/5.
