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         Rule:MF_00536};
CC   -!- COFACTOR:
CC       Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_00536};
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_00536};
CC       Name=Co(2+); Xref=ChEBI:CHEBI:48828; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_00536};
CC       Note=Binds 1 divalent metal cation per subunit. Can use ions such as
CC       Zn(2+), Mg(2+) or Co(2+). {ECO:0000255|HAMAP-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}.
