CC ChEBI:CHEBI:15378, ChEBI:CHEBI:57540, ChEBI:CHEBI:57945,
CC ChEBI:CHEBI:58538, ChEBI:CHEBI:58766; EC=1.1.1.290;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01825};
CC -!- PATHWAY: Cofactor biosynthesis; pyridoxine 5'-phosphate biosynthesis;
CC pyridoxine 5'-phosphate from D-erythrose 4-phosphate: step 2/5.
CC {ECO:0000256|HAMAP-Rule:MF_01825}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_01825}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_01825}.
