CC -!- FUNCTION: Catalyzes the reversible conversion of 3-
CC phosphohydroxypyruvate to phosphoserine and of 3-hydroxy-2-oxo-4-
CC phosphonooxybutanoate to phosphohydroxythreonine. {ECO:0000256|HAMAP-
CC Rule:MF_00160}.
CC -!- CATALYTIC ACTIVITY:

CC Note=Binds 1 pyridoxal phosphate per subunit. {ECO:0000256|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:0000256|ARBA:ARBA00005099,
CC ECO:0000256|HAMAP-Rule:MF_00160, ECO:0000256|RuleBase:RU004505}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_00160}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00160}.
CC -!- SIMILARITY: Belongs to the class-V pyridoxal-phosphate-dependent
CC aminotransferase family. SerC subfamily.
CC {ECO:0000256|ARBA:ARBA00006904, ECO:0000256|HAMAP-Rule:MF_00160}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_00160}.
