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.

Sequence similarities

Belongs to the PdxA family.
