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         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}.
