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:0000255|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:58589; EC=2.6.99.2; Evidence={ECO:0000255|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:0000255|HAMAP-Rule:MF_00279}.
CC -!- SUBUNIT: Homooctamer; tetramer of dimers. {ECO:0000255|HAMAP-
CC Rule:MF_00279}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00279}.
CC -!- SIMILARITY: Belongs to the PNP synthase family. {ECO:0000255|HAMAP-
CC Rule:MF_00279}.
