Protein existence	Inferred from homology

General annotation (Comments)

Function	Catalyzes the NAD(P)-dependent oxidation of 4-(phosphohydroxy)-L-threonine (HTP) into 2-amino-3-oxo-4-(phosphohydroxy)butyric acid which spontaneously decarboxylates to form 3-amino-2-oxopropyl phosphate (AHAP) By similarity. HAMAP-Rule MF_00536
Catalytic activity	4-phosphonooxy-L-threonine + NAD+ = 3-amino-2-oxopropyl phosphate + CO2 + NADH. HAMAP-Rule MF_00536
Cofactor	Binds 1 divalent metal cation per subunit. Can use ions such as zinc, magnesium or cobalt By similarity.
Pathway	Cofactor biosynthesis; pyridoxine 5'-phosphate biosynthesis; pyridoxine 5'-phosphate from D-erythrose 4-phosphate: step 4/5. HAMAP-Rule MF_00536
Subunit structure	Homodimer By similarity. HAMAP-Rule MF_00536
Subcellular location	Cytoplasm By similarity HAMAP-Rule MF_00536.
Miscellaneous	The active site is located at the dimer interface By similarity. HAMAP-Rule MF_00536
Sequence similarities	Belongs to the PdxA family.
