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=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00536};
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00536};
CC Name=Co(2+); Xref=ChEBI:CHEBI:48828;
CC Evidence={ECO:0000255|HAMAP-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}.
