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 -!- PATHWAY: Cofactor biosynthesis; pyridoxine 5'-phosphate biosynthesis;
CC pyridoxine 5'-phosphate from D-erythrose 4-phosphate: step 3/5.
CC {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-
