CC   -!- FUNCTION: Catalyzes the NAD(P)-dependent oxidation of 4-(phosphooxy)-L-
CC       threonine (HTP) into 2-amino-3-oxo-4-(phosphooxy)butyric acid which
CC       spontaneously decarboxylates to form 3-amino-2-oxopropyl phosphate
CC       (AHAP). {ECO:0000255|HAMAP-Rule:MF_00536}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=4-(phosphooxy)-L-threonine + NAD(+) = 3-amino-2-oxopropyl
CC         phosphate + CO2 + NADH; Xref=Rhea:RHEA:32275, ChEBI:CHEBI:16526,
CC         ChEBI:CHEBI:57279, ChEBI:CHEBI:57540, ChEBI:CHEBI:57945,
CC         ChEBI:CHEBI:58452; EC=1.1.1.262; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_00536};
CC   -!- COFACTOR:
CC       Name=a divalent metal cation; Xref=ChEBI:CHEBI:60240;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00536};
CC       Note=Binds 1 divalent metal cation per subunit. {ECO:0000255|HAMAP-
CC       Rule:MF_00536};
CC   -!- PATHWAY: Cofactor biosynthesis; pyridoxine 5'-phosphate biosynthesis;
CC       pyridoxine 5'-phosphate from D-erythrose 4-phosphate: step 4/5.
CC       {ECO:0000255|HAMAP-Rule:MF_00536}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00536}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00536}.
CC   -!- MISCELLANEOUS: The active site is located at the dimer interface.
CC       {ECO:0000255|HAMAP-Rule:MF_00536}.
CC   -!- SIMILARITY: Belongs to the PdxA family. {ECO:0000255|HAMAP-
CC       Rule:MF_00536}.
