CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01640};
CC   -!- PATHWAY: Cofactor biosynthesis; pyridoxine 5'-phosphate biosynthesis;
CC       pyridoxine 5'-phosphate from D-erythrose 4-phosphate: step 1/5.
CC       {ECO:0000255|HAMAP-Rule:MF_01640}.
CC   -!- SUBUNIT: Homotetramer. {ECO:0000255|HAMAP-Rule:MF_01640}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01640}.
CC   -!- SIMILARITY: Belongs to the glyceraldehyde-3-phosphate dehydrogenase
CC       family. Epd subfamily. {ECO:0000255|HAMAP-Rule:MF_01640}.
