CC -!- FUNCTION: Catalyzes the reversible conversion of 3-
CC phosphohydroxypyruvate to phosphoserine and of 3-hydroxy-2-oxo-4-
CC phosphonooxybutanoate to phosphohydroxythreonine. {ECO:0000255|HAMAP-
CC Rule:MF_00160}.
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 Evidence={ECO:0000255|HAMAP-Rule:MF_00160};
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; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_00160};
CC -!- COFACTOR:
CC Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00160};
CC Note=Binds 1 pyridoxal phosphate per subunit. {ECO:0000255|HAMAP-
CC Rule:MF_00160};
CC -!- PATHWAY: Amino-acid biosynthesis; L-serine biosynthesis; L-serine from
CC 3-phospho-D-glycerate: step 2/3. {ECO:0000255|HAMAP-Rule:MF_00160}.
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00160}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00160}.
CC -!- SIMILARITY: Belongs to the class-V pyridoxal-phosphate-dependent
CC aminotransferase family. SerC subfamily. {ECO:0000255|HAMAP-
CC Rule:MF_00160}.
