CC -!- FUNCTION: Catalyzes the reversible conversion of 3-
CC phosphohydroxypyruvate to phosphoserine and of 3-hydroxy-2-oxo-4-
CC phosphonooxybutanoate to phosphohydroxythreonine.
CC {ECO:0000250|UniProtKB:P10658}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2-oxoglutarate + O-phospho-L-serine = 3-phosphooxypyruvate +
CC L-glutamate; Xref=Rhea:RHEA:14329, ChEBI:CHEBI:16810,
CC ChEBI:CHEBI:18110, ChEBI:CHEBI:29985, ChEBI:CHEBI:57524; EC=2.6.1.52;
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2-oxoglutarate + 4-(phosphooxy)-L-threonine = (R)-3-hydroxy-2-
CC oxo-4-phosphooxybutanoate + L-glutamate; Xref=Rhea:RHEA:16573,
CC ChEBI:CHEBI:16810, ChEBI:CHEBI:29985, ChEBI:CHEBI:58452,
CC ChEBI:CHEBI:58538; EC=2.6.1.52;
CC -!- COFACTOR:
CC Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC Evidence={ECO:0000250};
CC Note=Binds 1 pyridoxal phosphate per subunit. {ECO:0000250};
CC -!- PATHWAY: Amino-acid biosynthesis; L-serine biosynthesis; L-serine from
CC 3-phospho-D-glycerate: step 2/3.
CC -!- PATHWAY: Cofactor biosynthesis; pyridoxine 5'-phosphate biosynthesis;
CC pyridoxine 5'-phosphate from D-erythrose 4-phosphate: step 3/5.
CC -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the class-V pyridoxal-phosphate-dependent
CC aminotransferase family. SerC subfamily. {ECO:0000305}.
