Med. 25:1442-1452(2019). CC -!- FUNCTION: Catalyzes the complicated ring closure reaction between the CC two acyclic compounds 1-deoxy-D-xylulose-5-phosphate (DXP) and 3-amino- CC 2-oxopropyl phosphate (1-amino-acetone-3-phosphate or AAP) to form CC pyridoxine 5'-phosphate (PNP) and inorganic phosphate. CC {ECO:0000256|HAMAP-Rule:MF_00279}. CC -!- CATALYTIC ACTIVITY: CC Reaction=1-deoxy-D-xylulose 5-phosphate + 3-amino-2-oxopropyl phosphate CC = H(+) + 2 H2O + phosphate + pyridoxine 5'-phosphate; CC Xref=Rhea:RHEA:15265, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, CC ChEBI:CHEBI:43474, ChEBI:CHEBI:57279, ChEBI:CHEBI:57792, CC ChEBI:CHEBI:58589; EC=2.6.99.2; Evidence={ECO:0000256|HAMAP- CC Rule:MF_00279}; CC -!- PATHWAY: Cofactor biosynthesis; pyridoxine 5'-phosphate biosynthesis; CC pyridoxine 5'-phosphate from D-erythrose 4-phosphate: step 5/5. CC {ECO:0000256|HAMAP-Rule:MF_00279}. CC -!- SUBUNIT: Homooctamer; tetramer of dimers. {ECO:0000256|HAMAP- CC Rule:MF_00279}. CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00279}. CC -!- SIMILARITY: Belongs to the PNP synthase family. {ECO:0000256|HAMAP- CC Rule:MF_00279}. CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_00279}. CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ CC whole genome shotgun (WGS) entry which is preliminary data. CC {ECO:0000313|EMBL:MRY11720.1}.
